Gabby has 4 times as many pencils as Kathy. Kathy has
45 as many pencils as Jean. If the three of them have a total of 150 pencils, how many pencils does Gabby have?
Gabby |
Kathy |
Jean |
4x4 |
1x4 |
|
|
4x1 |
5x1 |
16 u |
4 u |
5 u |
The number of pencils that Kathy has is repeated. Make the number of pencils that Kathy has the same. LCM of 1 and 4 is 4.
Total number of pencils that the three of them have
= 16 u + 4 u + 5 u
= 25 u
25 u = 150
1 u = 150 ÷ 25 = 6
Number of pencils that Gabby has
= 16 u
= 16 x 6
= 96
Answer(s): 96
