When adding or subtracting fractions do you change the numerator?
you subtract the numerator but the denominator stays the same.
What did you learn from adding and subtracting fractions?
I learned to always change the denominators before adding or subtracting the numerators. You must always have a common denominator before adding or subtracting.
How can you change a mix number to a fraction?
by multiplying the denominator with the whole number and adding the numerator. the denominator will remain the same.
How sustract fractions?
Determine the lowest common denominator. Multiply the numerator and denominator of each fraction by a number that will result in the denominator becoming the LCD. The purpose for multiplying both the numerator and denominator is that any number divided by itself = 1, and when you multiply something by 1, you don't change it. When subtracting two fractions with the same denominators, the first numerator minus the second numerator equals the numerator of the result, and the result has the same denominator (the LCD). Simplify.
Do you have to change the denominators when multiplying fractions?
No. To multiple fractions multiple the numerators together and multiply the denominators together and simplify (by dividing both numerator and denominator of the result by common factors until the only common factor is 1). The denominators only need to be the same when adding or subtracting fractions.

What is 2 out of 3 plus 3 out of 8?
When adding or subtracting Fractions you need "A Common Denominator (The Denominator is the bottom number and Numerator is the top) " For example 3 and 8 are the denominators and they both go into 24, so you would do 3x8=24 and 8x3=24 Then what ever you do to the bottom you do to the top 2x8=16 and 3x3=9 The question would be 16/24 + 9/24 When adding you do not change the denominator ,but you add the numerator. The answer would be 16/24 + 9/24 = 1 and 1/24
How do you change the denominator?
Multiply the numerator and the denominator by the same number and you can change it to whatever number you need.
