Linda and Gwen shared some marbles. Linda had 60% of what Gwen had at first. Linda then gave Gwen
37 of what she had. How many less percent did Linda have than Gwen in the end? Correct the answer to 1 decimal place.

Gwen |
Comparing Linda and Gwen 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 marbles that Linda had at first is repeated. Make the number of marbles that Linda had at first the same. LCM of 5 and 7 is 35.
Number of marbles that Gwen had in the end
= 21 u + 15 u
= 36 u
Number of less marbles that Linda had than Gwen in the end
= 36 u - 20 u
= 16 u
Number of less marbles that Linda had than Gwen in the end in percent
=
1636 x 100%
≈ 44.4%
Answer(s): 44.4%
