Avery jumped over 15 hurdles. If these hurdles are 60% of the hurdles in the race, how many hurdles are there in all?

40/100*15

cancel 100 and 15

40/20*3

120/20

6 hurdles is 40%

6+15=21 hurdles

there are 21 hurdles.

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!
