Sarah had
45 as many caramel apples as Fred. Fred had
47 as many caramel apples as Billy. If Billy had 57 more caramel apples than Sarah, find the total number of caramel apples that was shared among these 3 children at first.
Sarah |
Fred |
Billy |
4x4 |
5x4 |
|
|
4x5 |
7x5 |
16 u |
20 u |
35 u |
Fred is the repeated identity.
LCM of 5 and 4 = 20
Number of more caramel apples that Billy had more than Sarah
= 35 u - 16 u
= 19 u
19 u = 57
1 u = 57 ÷ 19 = 3
Total number of caramel apples
= 16 u + 20 u + 35 u
= 71 u
= 71 x 3
= 213
Answer(s): 213
