Answer:

22/35

Step-by-step explanation:

Simplify the following:

((1 + 4/7)×2)/5

((1 + 4/7)×2)/5 = ((1 + 4/7)×2)/5:

((1 + 4/7)×2)/5

Put 1 + 4/7 over the common denominator 7. 1 + 4/7 = 7/7 + 4/7:

((7/7 + 4/7) 2)/5

7/7 + 4/7 = (7 + 4)/7:

(((7 + 4)/7)×2)/5

7 + 4 = 11:

(11/7×2)/5

11/7×2 = (11×2)/7:

((11×2)/7)/5

((11×2)/7)/5 = (11×2)/(7×5):

(11×2)/(7×5)

7×5 = 35:

(11×2)/35

11×2 = 22:

Answer: 22/35
