Answer:

Explanation:
Thing of a number that when you will multiply it by 21, it would be equal or closest to 107 but not more than 107.
If you will multiply 5 by 21 you would get 105
So 5 would go on top.
Then you subtract 105 from 107
107-105 = 2
Since 21 would not fit into 2 this will be your remainder.
The remainder is what is left that you can no longer divide further. As a fraction, you would write the remainder as the numerator and the dividend as the denominator:
