Kimberly and Julie shared a bag of marbles. Kimberly had 20% as many marbles as Julie. When Julie gave 88 marbles to Kimberly, Kimberly had 10% more marbles than Julie. Find the total number of marbles the girls shared.
20% =
20100 =
15 10% + 100% = 110%
110% =

1x7 =
7 u |
5x7 =
42 u |
6x7 =
42 u |
| + 88 |
- 88 |
|
11x2 =
22 u |
10x2 =
20 u |
21x2 =
42 u |
The total remains unchanged.
LCM of 6 and 21 = 42
Number of marbles that Julie gave to Kimberly
= 42 u - 20 u
= 22 u
22 u = 88
1 u = 88 ÷ 22 = 4
Total number of marbles
= 42 u
= 42 x 4
= 168
Answer(s): 168
