Question

Sam gave jen 1/2 of his jujubes. Jen ate 1/2 of the jujubes and gave the rest to klye. Kyle kept 8 of the jujubes and gave the last 10 to Kim. How many jujubes did Jen eat? also explain how you got the answer

Answer 1

18 jujubes

Explanation:

The easiest way to solve this problem is to work backwards.

Kim has the last 10 jujubes.

If Kyle kept 8 jujubes after giving 10 to Kim, then Kyle had: 10 + 8 = 18 jujubes.

If Jen ate 1/2 of the jujubes and gave the rest to Kyle, then Kyle had 1/2 of Jen's jujubes. Therefore, Jen had 18 × 2 = 36 jujubes.

Therefore, Jen ate 18 jujubes.
