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

So he mowed 15 out of 60, or (I divided both numbers by 15)

this is equivalent to



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%!!

820,000 is the answr
