Gem has 3 times as many erasers as Kylie. Kylie has
56 as many erasers as Victoria. If the three of them have a total of 156 erasers, how many erasers does Victoria have?
Gem |
Kylie |
Victoria |
3x5 |
1x5 |
|
|
5x1 |
6x1 |
15 u |
5 u |
6 u |
The number of erasers that Kylie has is repeated. Make the number of erasers that Kylie has the same. LCM of 1 and 5 is 5.
Total number of erasers that the three of them have
= 15 u + 5 u + 6 u
= 26 u
26 u = 156
1 u = 156 ÷ 26 = 6
Number of erasers that Victoria has
= 6 u
= 6 x 6
= 36
Answer(s): 36
