Gillian and Abi had the
same number of sweets at first. Gillian gave 30 sweets away to her sister. In the end, Abi had four times as many sweets as Gillian. How many sweets did Gillian have at first?
| |
Gillian |
Abi |
| Before |
4 u |
4 u |
| Change |
- 30 |
|
| After |
1 u |
4 u |
The number of sweets that Abi had remains unchanged.
Number of sweets that Gillian gave away
= 4 u - 1 u
= 3 u
3 u = 30
1 u = 30 ÷ 3 = 10
Number of sweets that Gillian had at first
= 4 u
= 4 x 10
= 40
Answer(s): 40
