Abi has 2 times as many pens as Wendy. Wendy has
47 as many pens as Gabby. If the three of them have a total of 38 pens, how many pens does Gabby have?
Abi |
Wendy |
Gabby |
2x4 |
1x4 |
|
|
4x1 |
7x1 |
8 u |
4 u |
7 u |
The number of pens that Wendy has is repeated. Make the number of pens that Wendy has the same. LCM of 1 and 4 is 4.
Total number of pens that the three of them have
= 8 u + 4 u + 7 u
= 19 u
19 u = 38
1 u = 38 ÷ 19 = 2
Number of pens that Gabby has
= 7 u
= 7 x 2
= 14
Answer(s): 14
