Mr. Peter mowed 2/7 of his lawn. His son mowed 1/4 of it. Who mowed the most? How much of the lawn still need to be mowed?

Correct answer:

x =  0.4643

Step-by-step explanation:

$$\begin{gathered} p={\displaystyle \frac{2}{7}}={\displaystyle \frac{2}{7}}\doteq 0.2857 \\ s={\displaystyle \frac{1}{4}}=0.25 \\ p>s \\ x=1-p-s=1-0.2857-0.25={\displaystyle \frac{13}{28}}=0.4643 \end{gathered}$$
