Question

kevin completed 10 problems of his homework during lunch this is 2/7 of the total assignment how many problem was Kevin assigned for homework

Answer 1

35 problems

Explanation:

We know that 10 problems are 2/7 of his total assignment, so we can set up the following equation,

`(10)/(x\\) = (2)/(7)`

(side note: x is the denominator because we don't know how many problems it is out of yet)

We can cross multiply which gives us: (7x10) and 2(x)

70 = 2x (set them equal)

x = 35 (divide 70 by 2)

Hope this helps!
