Here, we will show you how to calculate how many nickels there are in 21 quarters.
First, calculate how many cents there are in 21 quarters by multiplying 21 by 25, and then
divide that result by 5 cents to get the answer.
Here is the math to illustrate better:
21 quarters x 25 cents
= 525 cents
525 cents / 5 cents
= 105 nickels
Thus, the answer to the question "How many nickels are in 21 quarters?" is as follows:
105 nickels
Note: We multiplied 21 by 25, because there are 25 cents in a quarter, and we divided 525 by 5, because there are 5 cents in a nickel.
