The ratio of Anthony's stamps to Emily's stamps at first was 3 : 5. After Anthony gave Emily 116 stamps, the ratio of Anthony's stamps to Emily's stamps is 1 : 3. What was the number of stamps they had in total?
| |
Anthony |
Emily |
Total |
| Before |
3x4 =
12 u |
5x4 =
20 u
|
8x4 =
32 u |
| Change |
- 116 |
+ 116 |
|
| After |
1x8 =
8 u |
3x8 =
24 u |
4x8 =
32 u |
Number of stamps that Anthony gave Emily
= 12 u - 8 u
= 4 u
4 u = 116
1 u = 116 ÷ 4 = 29
Total number of stamps that they had
= 32 u
= 32 x 29
= 928
Answer(s): 928
