You could set up a proportion to figure out the anwer. 15 hurdles/60%=X hurdles/100%. Cross multiply, 1500=60x. Divide by 60, 25=X=total amount of hurdles. Hope this helps!
Do a proportion First change 1/5 into a whole number first.Which is 1/5 times 60=12 Now do a proportion 14/12=x/60 12x=840 x=70 Simone can peel 70 potatoes in a hour.
