Division as Inverse Process of Multiplication
Multiplication and division are inverse processes.
See the pictures carefully.
15 cubical blocks are
arranged in 5 rows
and 3 columns. 15 ÷ 5 = 3 We can say that 15 blocks are
arranged equally in 3 columns.
We can also say that 15 blocks
15 ÷ 3 = 5
5 × 3 = 15 are arranged equally in 5 rows.
