2. 20 – 4 = 16 (4 is subtracted first time)
16 – 4 = 12 (4 is subtracted second time)
12 – 4 = 8 (4 is subtracted third time)
8 – 4 = 4 (4 is subtracted fourth time)
4 – 4 = 0 (4 is subtracted fifth time)
We say 20 ÷ 4 = . ( divided by is )
Division Using Number Line
Suppose we have to divide 8 by 2.
4 3 2 1
0 1 2 3 4 5 6 7 8 9 10
We start from 8 and hop back 2 units at a time till we reach 0.
We note that it took 4 hops to reach 0.
Hence 8 ÷ 2 = 4 [number of hops is the answer]
A. Fill in the blanks.
