Question

Miss Jones mowed 1/4 of her lawn her son mowed 2/5 of it. who mowed most of the lawn? how much of the lawn still needs to be mowed

Answer 1

Answer:

The son mowed most of the lawn

7/20 of the lawn still needs to be mowed

Explanations:

Size of the lawn mowed by Miss Jones = 1/4

Size of the lawn mowed by her son = 2/5

To know who mowed the most lawn, find the LCM of the denominators

The LCM of 4and 5 = 20

Make the denominators of both fractions to be 20

Size of the lawn mowed by Miss Jones = 1/4 x 5/5 = 5/20

Size of the lawn mowed by her son = 2/5 x 4/4 = 8/20

Since 8/20 > 5/20, Miss Jone's son mowed more part of the lawn than Miss Jone

How much of the lawn still needs to be mowed:

`\begin{gathered} \text{The part of the lawn that still n}eeds\text{ to be mowed = 1 -}(1)/(4)-(2)/(5)\text{ } \\ \text{The part of the lawn that still n}eds\text{ to be mowed = }(7)/(20) \end{gathered}`
