What is a fraction plus a fraction equal when simplifed?

Answer 1

It depends on the 2 fractions, but let me give you and example.

1st fraction- 2/5 . (2 is the numerator, 5 is the denominator).

2nd fraction-2/10. (2 is the numerator, 10 is the denominator).

First when you add fractions you want to make sure the denominator (or the number below the line) is the same. So in order to do that, you would find the least common multiple (a number they are both divisible by.

5 and 10 can both be divisible by 10, so our denominator is going to be 10. To change the denominator you want to multiply 5 by 2 to get 10. Whatever you do to the denominator (5), you would do to the numerator.

2*2

5*2

10

Once you have the same denominator, all you do is add the numerators together and keep the denominator the same.

--- + --- = ---

10

10

To simplify, think of a number that both the numerator and the denominator can both be divided by (that doesn't give you a decimal.

In this case, 6 and 10 are both divisible by 2, so you would divide both of them by 2

6/10 = 3/5

And there you have it! You know when the fraction is simplified when the numerator and the denominator are not divisible by one number.
