Question

What is the remainder of 21 divided by 4

Answer 1

1 because 21/4= r=1

5*4=20 so your remainder is 1

Answer 2

21 ÷ 4 = 5 with a remainder of 1.

5 × 4 = 20

21 - 20 = 1

If you keep going despite the remainder, you will get 5 1/4. However, you need not do this if you only want the remainder.
