Comparing Zoe
and Esther at first |
5x8 =
40 u |
1x8 =
8 u |
| Before |
8x5 =
40 u |

| Change |
- 7x5 =
- 35 u |
+ 7x5 =
+ 35 u |
| After |
1x5 =
5 u |
43 u |
20% =
20100 =
15The number of coins that Zoe had at first is repeated. Make the number of coins that Zoe had at first the same. LCM of 5 and 8 is 40.
Number of coins that Esther had in the end
= 8 u + 35 u
= 43 u
Number of less coins that Zoe had than Esther in the end
= 43 u - 5 u
= 38 u
Number of less coins that Zoe had than Esther in the end in percent
=
3843 x 100%
≈ 88.4%
Answer(s): 88.4%
