Jade |
Diana |
Comparing Jade and Diana at first |
5x7 = 35 u |
3x7 = 21 u |
Before |
7x5 = 35 u |
|
Change |
- 3x5 = - 15 u |
+ 3x5 = + 15 u |
After |
4x5 = 20 u |
36 u |
60% =
60100 =
35The number of coins that Jade had at first is repeated. Make the number of coins that Jade had at first the same. LCM of 5 and 7 is 35.
Number of coins that Diana had in the end
= 21 u + 15 u
= 36 u
Number of less coins that Jade had than Diana in the end
= 36 u - 20 u
= 16 u
Number of less coins that Jade had than Diana in the end in percent
=
1636 x 100%
≈ 44.4%
Answer(s): 44.4%
