Answer 1

Let x be the faction of a whole lawn that can be mowed in one hour. Solve the following equation for x:\[\frac{1}{4+\frac{8}{18}}=\frac{x}{1}\]The expression above can be verbalized as follows:
"If the lawn can be mowed by John and Tim in 4 and 8/18 ths hours, then they can mow x of it in one hour.\[x=\frac{9}{40} \text{ of one lawn} \]
