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?

Answer 1

Jen ate 18 jujubes

Explanation:

Start with Kim. She was given 10. There is no remainder.

Kyle kept 8 from the total he was given, so Kyle had 18.

Let the number of Jujubes given to Jen = x

(1/2) x = 18 Multiply both sides by 2

2(1/2)x = 18*2

x = 36

Jen ate 1/2 of 36 which was 18.

Though you are not asked, Sam must have begun this with 2*36 = 72 Jujubes.
