lou makes pancakes at a pancake house. he makes 12 pancakes in 4 minutes. at a rate, how long would it take him to make 54 pancakes
12/4 = 3 pancakes per minute
54/3 = _______ minutes
To find out how long it would take Lou to make 54 pancakes, we can set up a proportion to compare the number of pancakes he makes to the time it takes.
Let "x" be the time it takes for Lou to make 54 pancakes. We know that he makes 12 pancakes in 4 minutes, so we can set up the following proportion:
12 pancakes / 4 minutes = 54 pancakes / x minutes
To solve for "x," we can cross-multiply:
12x = 4 * 54
12x = 216
Now, divide both sides of the equation by 12 to solve for "x":
x = 216 / 12
x = 18
Therefore, it would take Lou 18 minutes to make 54 pancakes at the same rate.
