Gabby has 3 times as many pencils as Yen. Yen has
25 as many pencils as Diana. If the three of them have a total of 130 pencils, how many pencils does Gabby have?
Gabby |
Yen |
Diana |
3x2 |
1x2 |
|
|
2x1 |
5x1 |
6 u |
2 u |
5 u |
The number of pencils that Yen has is repeated. Make the number of pencils that Yen 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 = 130
1 u = 130 ÷ 13 = 10
Number of pencils that Gabby has
= 6 u
= 6 x 10
= 60
Answer(s): 60
