Min has 2 times as many pencils as Gem. Gem has
34 as many pencils as Sabrina. If the three of them have a total of 91 pencils, how many pencils does Sabrina have?
| Min |
Gem |
Sabrina |
| 2x3 |
1x3 |
|
| |
3x1 |
4x1 |
| 6 u |
3 u |
4 u |
The number of pencils that Gem has is repeated. Make the number of pencils that Gem has the same. LCM of 1 and 3 is 3.
Total number of pencils that the three of them have
= 6 u + 3 u + 4 u
= 13 u
13 u = 91
1 u = 91 ÷ 13 = 7
Number of pencils that Sabrina has
= 4 u
= 4 x 7
= 28
Answer(s): 28
