Gem and Emma had the
same number of sweets at first. Gem gave 20 sweets away to her brother. In the end, Emma had five times as many sweets as Gem. How many sweets did Gem have at first?

| Before |
5 u |
5 u |
| Change |
- 20 |
|
| After |
1 u |
5 u |
The number of sweets that Emma had remains unchanged.
Number of sweets that Gem gave away
= 5 u - 1 u
= 4 u
4 u = 20
1 u = 20 ÷ 4 = 5
Number of sweets that Gem had at first
= 5 u
= 5 x 5
= 25
Answer(s): 25
