Question

Hello im ganna do fraccions what is 13\15 + 8\3 + 2\9 =

Answer 1

169/45

Explanation:

First lets do 13/15 + 8/3.

We can multiply 8/3 by 5 to both num and denom for a ration, with the denominator being 15: 40/15.

Then add 13/15 to 40/15 to get 53/15

Now multiply that by 3 to both num and denom to get 159/45. This is to get the least common factor with 9.

2/9 can be multiplied by 5 to both num and denom to get the least common factor with 15: 10/45

Now add 159/45 with 10/45 = 169/45

169/45 is the least it can be simplified so that is the answer.

Answer 2

3 34/45

Explanation:

The common denominator of these is 45.

13/15 = 39/45

8/3 = 120/45

2/9 = 10/45

Add that up and that is 169/45

Simplify as a mixed number, and it would be 3 34/45
