Answer 1

Answer: 1. 8/35 2. 11/35

Step-by-step explanation:

1. If the first expression you have to solve the parentheses first the multiply is by 2/7

so
`(1)/(5) + (3)/(5)` = 4/5

`(4)/(5) * (2)/(7)` =
`(8)/(35)`

2. You have to multiply first before you add in the second one using the rules of pemdas.

3/5 * 2/7 = 6 / 35

Now add 6/35 and 1/5

`(1)/(5) + (6)/(35)` To add them they have to have the same denominators so we will multiply 5 by 7 to get 35 and the same as the top one.

`(7)/(35) +(6)/(35)` = 13/35

Answer 2

1. 8/35

2. 13/35

Step-by-step explanation:

You add the numbers in the parentheses first, then you multiply

1. 1/5 + 3/5 = 4/5

4/5 * 2/7 = 8/35

———————————

2. 1/5 + 3/5 * 2/7

You would multiply 3/5 and 2/7 first

1/5 + 6/35

Then you find a common denominator

1/5 = 7/35

Then you add 7/35 and 6/35

7/35 + 6/35 = 13/35
