Anna and Abi shared some pens. Anna had 70% of what Abi had at first. Anna then gave Abi
45 of what she had. How many less percent did Anna have than Abi in the end? Correct the answer to 1 decimal place.

Anna |
Abi |
Comparing Anna and Abi at first |
10x1 = 10 u |
7x1 = 7 u |
Before |
5x2 = 10 u |
|
Change |
- 4x2 = - 8 u |
+ 4x2 = + 8 u |
After |
1x2 = 2 u |
15 u |
70% =
70100 =
710The number of pens that Anna had at first is repeated. Make the number of pens that Anna had at first the same. LCM of 10 and 5 is 10.
Number of pens that Abi had in the end
= 7 u + 8 u
= 15 u
Number of less pens that Anna had than Abi in the end
= 15 u - 2 u
= 13 u
Number of less pens that Anna had than Abi in the end in percent
=
1315 x 100%
≈ 86.7%
Answer(s): 86.7%
