Question

Mr. Ramirez informs the students that some of the trees they plant will not survive their first year, so the class will take precautions to monitor the trees to give them the best chance of survival.

Abby does some research and finds that, on average, 3 out of every 25 trees planted will die their first year.



What percentage of the trees will survive their first year?

Answer 1

88%

Explanation:

Since 25 is 1/4 of 100, you can simply subtract 3 from 25 and then, your answer from that you want to multiply it by 4. Or you can make it into a fraction if that helps you visualize what's going on. It'll be 22 over 25, now multiply both numerator and denominator by 4.

Answer 2

The percentage of trees that will survive are 26%
