Question

Mr. Ito is spreading mulch in his yard. He spreads 4 2/3 square yards in 2 hours. How many square yards can he mulch per hour?

Answer 1

`2 1/3" square yards"`

Explanation:

`2" hours "to 4 2/3`

`1" hour"to 4 2/3÷2`

To divide, first convert `4 2/3" to an improper fraction"`

`rArr4 2/3=14/3`

We now have `14/3÷2/1`

The remaining steps are.

• leave the first fraction

• change division to multiplication

• Invert the second fraction (turn upside down )

• Cancel, if possible and simplify

`rArr14/3xx1/2larr" multiply and invert"`

`=cancel(14)^7/3xx1/cancel(2)^1larr" cancelling"`

`=(7xx1)/(3xx1)=7/3=2 1/3`

He can spread `2 1/3` square yards of mulch in 1 hour working at the same rate.
