Roshel has 2 times as many pens as Min. Min has
56 as many pens as Lynn. If the three of them have a total of 42 pens, how many pens does Roshel have?
| Roshel |
Min |
Lynn |
| 2x5 |
1x5 |
|
| |
5x1 |
6x1 |
| 10 u |
5 u |
6 u |
The number of pens that Min has is repeated. Make the number of pens that Min has the same. LCM of 1 and 5 is 5.
Total number of pens that the three of them have
= 10 u + 5 u + 6 u
= 21 u
21 u = 42
1 u = 42 ÷ 21 = 2
Number of pens that Roshel has
= 10 u
= 10 x 2
= 20
Answer(s): 20
