Comparing Victoria
and Eva at first |
10x7 =
70 u |
7x7 =
49 u |
| Before |
7x10 =
70 u |
|
| Change |
- 5x10 =
- 50 u |
+ 5x10 =
+ 50 u |
| After |
2x10 =
20 u |
99 u |
70% =
70100 =
710The number of pens that Victoria had at first is repeated. Make the number of pens that Victoria had at first the same. LCM of 10 and 7 is 70.
Number of pens that Eva had in the end
= 49 u + 50 u
= 99 u
Number of less pens that Victoria had than Eva in the end
= 99 u - 20 u
= 79 u
Number of less pens that Victoria had than Eva in the end in percent
=
7999 x 100%
≈ 79.8%
Answer(s): 79.8%
