120 cookies
Step-by-step explanation:
3 / (3/4) = 4
30 * 4 = 120
Answer:
120
Step-by-step explanation:
3/4 of an hour is the same as 45 minutes. If she is doing this in an even pace, we can figure out how many cookies she's made in 15 minutes. (This will make the problem easier for us to solve.)
45÷3=15
30÷3=10
We now that in 15 minutes she can make 10 cookies. There are 180 minutes in three hours so we can divide 180 by 15 to know how many rounds of 15 there is.
180÷15 =12
Know we know that there are 12 rounds of 15 in three hours. We also know that in 15 minutes she can make ten cookies so all we have to do now is to multiply 12×10 to get 120. She can make 120 cookies in three hours.
