Step-by-step explanation:

7 + 3^2 - 2 * 5 = (3/4 + 1/8) : 1/8

7 + 9 - 10 = 7/8 : 1/8

6 = 7/8 * 8

6 = 7

(7 + 3^2 - 2 * 5) < (3/4 + 1/8) : 1/8

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
