Question

henry has 15 lawns mowed out of 60 lawns.What percent of the lawns does henry still have to mow?show the model

Answer 1

so he mowed 15 out of 60, or
`(15)/(60) = (1)/(4)` (I divided both numbers by 15)

this is equivalent to


`(1)/(4)*100%=25%`

in order to calculate the percentage,just multiply the number by 100 %, which is actually equal to 1!

so, he mowed 25 and he still needs to do 100-25=75%!!
