Laura jumped 2.3 meters in the high jump. Lucy jumped 20% lower. How high was Laura's jump?

Well... because you need to find 20 percent try looking for a lower number like 10 percent 10 percent is 0.23 and double that is 0.46 which is 20 percent higher and so she Laura jumped 0.46m higher than Lucy!
so Laura jumped 0.46m higher

Laura jumped 2.3 meters high, and Lucy jumped 20% lower, which is 1.84 meters. To calculate this, we found that 20% of 2.3 meters is 0.46 meters, and subtracting this from Laura's jump gives Lucy's height. Therefore, Lucy's jump was 1.84 meters.
