How to find Sarah’s best jump:
First you multiply 4.25 by 12% (or 0.12) to get 0.51 meters.
4.25 + 0.51 = 4.76 meters. So her best jump is 4.76 meters.
How to find the winning jump:
Since her best jump is 15% less than the winning jump, it must be 85% of the winning jump (as in 85 is 85% of 100).
So you divide 4.76 by 85% (or 0.85) which equals 5.6 meters.
So, the winning jump was 5.6 meters.
