What if the denominator is different?

What if the denominator is different?

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

Does the denominator change when subtracting?

To add or subtract fractions they must have the same denominator (the bottom value). If the denominators are already the same then it is just a matter of either adding or subtracting the numerators (the top value).

What if the denominator is not the same?

Adding Fractions: If the denominators are not the same, you must find the common denominator by finding the least common multiple (LCM). Subtracting Fractions: If the denominators are not the same, you must find the common denominator by finding the least common multiple (LCM).

Does the denominator change when multiplying?

First you multiply the numerators, then you multiply the denominators, even if they’re not alike. Unlike denominators means the bottom numbers are different from each other.

How do you change denominators to the same?

To make the denominators the same we can: Multiply top and bottom of each fraction by the denominator of the other. We simplified the fraction 2032 to 1016 , then to 58 by dividing the top and bottom by 2 each time, and that is as simple as it can get!

Why does the denominator stay the same when adding fractions?

The denominator will always stay the same because the size of the equal pieces does not change when you combine the two fractions together. They have the same denominator, so they can be combined together. Add the numerators (1 + 6 = 7).

Do you multiply the numerator or denominator?

Rule for Multiplication of Fractions When multiplying fractions, simply multiply the numerators together and then multiply the denominators together. Simplify the result. This works whether the denominators are the same or not. If you multiply the fractions 3/2 and 4/3 together, you get 12/6.

When multiplying fractions does the denominator stay the same?

Multiplication of fractions do not require the same denominator, or the bottom number of the fraction, like addition and subtraction does. Instead, you would simply multiply the denominators and the top numerators.
