| Before |
5x4 =
20 u |
4 u |
| Change |
- 4x4 =
- 16 u |
- 3 u |
| After |
1x4 =
4 u |
1 u |

4 u |
1 u |
The number of jelly beans that Hilda had in the end is repeated. Make the number of jelly beans that Hilda had in the end the same. LCM of 1 and 4 is 4.
Number of jelly beans that Ivory had less than Hilda
= 20 u - 4 u
= 16 u
16 u = 80
1 u = 80 ÷ 16 = 5
Number of jelly beans that Hilda had at first
= 20 u
= 20 x 5
= 100
Answer(s): 100
