Fraction questions can look tricky at first, but they become easier with practice and know-how. Start by learning the terminology and fundamentals, then pratice adding, subtracting, multiplying, problem solving fraction, and dividing fractions. Once you understand what fractions are and how to manipulate them, you'll be breezing through fraction problems in no time. Tip: Typically, you'll need to convert mixed numbers to improper fractions if you're multiplying or dividing them.

To solve a fraction multiplication question in math, line up the 2 fractions next to each other. Multiply the top of the left fraction by the top of the right fraction and write that answer on top, then multiply the bottom of each fraction and write that answer on the bottom, problem solving fraction. Simplify the new fraction as much as possible. To divide fractions, flip one of the fractions upside-down and multiply them the same way. If you need to add or subtract fractions, keep reading!

This article was co-authored by our trained team of editors and researchers who validated it for accuracy and comprehensiveness.

Together, they cited information from 10 references, problem solving fraction. Categories: Fractions. This article has overviews, and 17 testimonials from our readers, earning problem solving fraction our reader-approved status. Learn more Method 1. Note that the numerator is on the top and the denominator is on the bottom. Fractions refer to parts of a whole, and the top number in a fraction is called the numerator, problem solving fraction. This tells you how many parts of the whole you're working with.

The bottom number in a fraction is referred to as the denominator and tells you how many parts make up a whole. Turn a whole number into a fraction by putting it over 1. If you have a whole number and need to convert it to a fraction, you can use the whole number as the numerator. Always use 1 as the denominator since every undivided whole has a single part. Reduce fractions if you need to simplify them.

Start by finding the greatest common factor GCF of the numerator and denominator. The GCF is the largest number that both the numerator and denominator can be divided by. Then, just divide both the problem solving fraction and the denominator by the greatest common factor to reduce the fraction. Divide 15 by 15, which is 1, so that's problem solving fraction new numerator.

Divide 45 by 15, which is 3, so that's your new denominator. Learn to turn mixed numbers into improper fractions. A mixed number has both a whole number and a fraction.

To solve certain fraction questions more easily, you might need to turn the mixed number into an improper fraction meaning the number on top problem solving fraction larger than the number on the bottom. You can do this by multiplying the whole number by the denominator and adding this number to the numerator.

Put the new numerator over the denominator. Stary by multiplying 3 by 1, which is 3. Add 3 to 2, the problem solving fraction numerator. Figure out how to convert improper fractions into mixed numbers. Sometimes, you might have the opposite problem and need to make an improper fraction a mixed number.

Start by figuring out how many times the numerator can problem solving fraction into the denominator using division. This becomes your whole number. Find the remainder by multplying the whole number by the divisor the number you're dividing by and subtracting the result from the dividend the number you're dividing up.

Put the remainder over the original denominator. The number 4 goes into 17 a total of 4 times, so the whole number is 4. Then, multiply 4 by 4, problem solving fraction, which is equal to Subtract 16 from 17, which is equal to 1, so that's the remainder. Method 2. Add fractions with the same denominator by combining the numerators. To add fractions, they must have the same denominator.

If they do, problem solving fraction, simply add the numerators together. Subtract fractions with the same denominator by subtracting the numerators. If you need to subtract fractions, they must have the same denominator, just like if you were adding them. All you have to do is subtract the smaller numerator from the larger numerator to solve the problem.

Find a common multiple to add or subtract fractions without the same denominator. If the fractions don't have the same denominator, you'll need to find a common multiple of both denominators and convert each fraction so they have the same denominator. To do this, multiply both the numerator and denominator by the number that will convert it to the common multiple. Then, add or subtract the numerators to find the answer.

In this case, the common multiple is 6 since both 2 and 3 can be converted to 6. You don't need to convert the other fraction at all.

Just subtract 2 from 7, problem solving fraction is 5. Multiply fractions straight across, problem solving fraction.

Fortunately, multiplying fractions is pretty easy. If the fractions aren't already in the lowest terms, reduce them, problem solving fraction. Then, all you need to do is multiply problem solving fraction numerator by the numerator and the denominator by the denominator. Then, multpily 3 by 8, which is Divide fractions by flipping the second fraction upside down and multiplying straight across. To divide fractions, start by making the fraction you want to divide by a reciprocal.

Do this problem solving fraction turning it upside down so the numerator becomes the denominator and the denominator becomes the numerator. Then, multiply both numerators and both denominators together. Then just multiply 1 x 6 to find the numerator which is 6 and 2 x 1 to find the denominator which is 2.

Next, an easy way to divide would be to the reciprocal method. Yes No. Not Helpful 57 Helpful If the ratio of girls to boys isand there are boys, how do I calculate the total number of students? Assuming all the girls and boys are students.

Not Helpful 49 Helpful Not Helpful 36 Helpful Act like the whole number is also a fraction i. Then multiply it as you would two fractions.

Multiply the numerators or the top numbers and multiply the denominators or the bottom numbers, problem solving fraction. The fraction that results is your answer.

Not Helpful 35 Helpful To figure this out, you just have to know how to calculate percentages in general, which is actually quite simple, problem solving fraction. To convert a percentage into a decimal value, just move the decimal place two spaces to the left. So, problem solving fraction, Now, to find Not Helpful 37 Helpful Convert each fraction to an equivalent fraction with a denominator of 15, then compare numerators.

Not Helpful 33 Helpful He used two-thirds of a yard to hang up the first lantern. What part of a yard remained to hang the last four lanterns? Since 3 goes into problem solving fraction three times, you are going to multiply 3 times the top number in the second fraction, so 3x2 making the top number 6. I think John used too much string on that one!

Not Helpful 23 Helpful Write the fractions with a common denominator. Subtract the second numerator from the first numerator problem solving fraction put the answer above the common denominator. Not Helpful 32 Helpful Write the percentage as the numerator of a fraction.

Write as the denominator. Reduce the fraction to lowest terms if possible. Not Helpful 5 Helpful
