Comparing Vanessa and Gillian at first |
5x7 = 35 u |
2x7 = 14 u |
Before |
7x5 = 35 u |
|
Change |
- 4x5 = - 20 u |
+ 4x5 = + 20 u |
After |
3x5 = 15 u |
34 u |
40% =
40100 =
25The number of coins that Vanessa had at first is repeated. Make the number of coins that Vanessa had at first the same. LCM of 5 and 7 is 35.
Number of coins that Gillian had in the end
= 14 u + 20 u
= 34 u
Number of less coins that Vanessa had than Gillian in the end
= 34 u - 15 u
= 19 u
Number of less coins that Vanessa had than Gillian in the end in percent
=
1934 x 100%
≈ 55.9%
Answer(s): 55.9%
