Question

Zada needs to simplify the expression below. 72 – 4 × 12 ÷ 6 Which solution for Zada’s expression is correct?

F. 408, because 72 – 4 is 68, 12 ÷ 6 is 6, and 68 × 6 is 408

G. 64, because 4 × 12 is 48, 48 ÷ 6 is 8, and 72 – 8 is 64

H. 4, because 4 × 12 is 48, 72 – 48 is 24, and 24 ÷ 6 is 4

J. 136, because 72 – 4 is 68, 68 × 12 is 816, and 816 ÷ 6 is 136

Answer 1

order of operations matter here so

72 - 4 × 12 ÷ 6

start with 4 × 12 (which equals 48)

72 - 48 ÷ 6

next is 48 ÷ 6. (which equals 8)

72 - 8 = 64

so g is correct
