Question

Andrea is having a snowball fight. She made 6 piles of snowballs with 36 in each pile. How many more piles of snowballs will she need to make to have 360 snowballs total?​

Answer 1

4

Explanation:

6 × 36 = 216 current snowballs

360 - 216 = 144 snowballs needed to reach the sum

x × 36 = 144 ⇒ 144 ÷ 36 = 4 piles of snowballs left to make

Or, if you would rather write it down as an equation:

[360 - (6 × 36)] ÷ 36

⇒ (360 - 216) ÷ 36

⇒ 144 ÷ 36

⇒ 4.
