Solution
The correct option is A 5
Here, we have to divide 20 into 4 equal groups. We can do this using skip backward counting.
20 to 16
16 to 12
12 to 8
8 to 4
4 to 0
To reach 0, we did skip backward counting 5 times. Therefore, each shirt will have 5 buttons. This can also be expressed as:
20÷4=5
