The ratio of Emma's stickers to Benjamin's stickers at first was 3 : 5. After Emma gave Benjamin 88 stickers, the ratio of Emma's stickers to Benjamin's stickers is 1 : 3. What was the number of stickers they had altogether?
| |
Emma |
Benjamin |
Total |
| Before |
3x4 =
12 u |
5x4 =
20 u
|
8x4 =
32 u |
| Change |
- 88 |
+ 88 |
|
| After |
1x8 =
8 u |
3x8 =
24 u |
4x8 =
32 u |
Number of stickers that Emma gave Benjamin
= 12 u - 8 u
= 4 u
4 u = 88
1 u = 88 ÷ 4 = 22
Total number of stickers that they had
= 32 u
= 32 x 22
= 704
Answer(s): 704
