Vanessa has 4 times as many pencils as Dana. Dana has
23 as many pencils as Jaslyn. If the three of them have a total of 39 pencils, how many pencils does Vanessa have?
| Vanessa |
Dana |
Jaslyn |
| 4x2 |
1x2 |
|
| |
2x1 |
3x1 |
| 8 u |
2 u |
3 u |
The number of pencils that Dana has is repeated. Make the number of pencils that Dana has the same. LCM of 1 and 2 is 2.
Total number of pencils that the three of them have
= 8 u + 2 u + 3 u
= 13 u
13 u = 39
1 u = 39 ÷ 13 = 3
Number of pencils that Vanessa has
= 8 u
= 8 x 3
= 24
Answer(s): 24
