Total number of balls = 25
Number of balls in each group = 5
Number of groups formed = ?
Here, we have to divide 25 balls in groups of 5 balls each.
that is, we have to find the value of 25 ÷ 5.
We know, division is nothing but repeated subtraction.
To find the answer, we need to repeatedly subtract 5 from 25, until we get a zero.
