Wendy and Gabby had the same number of beads. After Wendy had given away 63 beads, Gabby had 4 times as many beads as Wendy. How many beads did each of them have at first?
| |
Wendy |
Gabby |
| Before |
1 u + 63 |
4 u |
| Change |
- 63 |
|
| After |
1 u |
4 u |
Number of beads that Gabby had remains unchanged.
Number of beads that Wendy and Gabby had at first is equal.
4 u = 1 u + 63
4 u - 1 u = 63
3 u = 63
1 u = 63 ÷ 3= 21
Number of beads that each of them had at first
= 1 u + 63
= 21 + 63
= 84
Answer(s): 84
