Emily has 4 times as many erasers as Yen. Yen has
47 as many erasers as Wendy. If the three of them have a total of 54 erasers, how many erasers does Emily have?
| Emily |
Yen |
Wendy |
| 4x4 |
1x4 |
|
| |
4x1 |
7x1 |
| 16 u |
4 u |
7 u |
The number of erasers that Yen has is repeated. Make the number of erasers that Yen has the same. LCM of 1 and 4 is 4.
Total number of erasers that the three of them have
= 16 u + 4 u + 7 u
= 27 u
27 u = 54
1 u = 54 ÷ 27 = 2
Number of erasers that Emily has
= 16 u
= 16 x 2
= 32
Answer(s): 32
