Answer:

72%

Step-by-step explanation:

Elise did 36 out of 50 problems in 1 hour. Another way to write 36 out of 50 is 36/50.

To find the percent from a fraction, one thing we can do is make the denominator 100 but still make the fraction the same, and then take the numerator.

We have 36/50, but want to make the denominator 100, not 50. We know that 100/50 = 2, so we have to multiply 50 by 2 to get 100.

Keeping the fraction equal, we can multiply 36/50 by 2/2 to get 72/100. We can do this because 2/2=1, so we are keeping the fraction the same -- just changing the numbers a little bit.

A fraction of form x/100 is equal to x%, so 72/100 = 72% as our answer
