Winnie has 3 times as many pencils as Raeann. Raeann has
25 as many pencils as Marion. If the three of them have a total of 91 pencils, how many pencils does Winnie have?
Winnie |
Raeann |
Marion |
3x2 |
1x2 |
|
|
2x1 |
5x1 |
6 u |
2 u |
5 u |
The number of pencils that Raeann has is repeated. Make the number of pencils that Raeann has the same. LCM of 1 and 2 is 2.
Total number of pencils that the three of them have
= 6 u + 2 u + 5 u
= 13 u
13 u = 91
1 u = 91 ÷ 13 = 7
Number of pencils that Winnie has
= 6 u
= 6 x 7
= 42
Answer(s): 42
