Answer:

1. 8/35

2. 13/35

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

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 [tex]\frac{1}{5} + \frac{3}{5}[/tex]   = 4/5

[tex]\frac{4}{5} * \frac{2}{7}[/tex] = [tex]\frac{8}{35}[/tex]    

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

[tex]\frac{1}{5} + \frac{6}{35}[/tex]  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.

[tex]\frac{7}{35} +\frac{6}{35}[/tex] = 13/35
