Question

1. abbie climbed a hill that had 600 steps each 1 ½ feet high. then she went back down 143 steps. how much height was lost when she went down the steps?

Explanation:

Step1: Convert mixed number to improper fraction

The height of each step is \(1\frac{1}{2}\) feet. Convert this to an improper fraction: \(1\frac{1}{2}=\frac{3}{2}\) feet.

Step2: Calculate height lost

To find the height lost, multiply the number of steps she went down (143) by the height of each step (\(\frac{3}{2}\) feet). So, \(143\times\frac{3}{2}=\frac{429}{2} = 214.5\) feet.

Answer:

214.5 feet
