What is the inverse operation of division?

The inverse operation of division is multiplication. In mathematics, the inverse operation of a given operation is the one that undoes the original operation. So, if you first divide a number by another number, you can undo that operation and get back to the original number by multiplying the result by the same number you divided by.

For example, if you have 10 ÷ 2 = 5, you can undo this division by multiplying 5 by 2, which gives you back the original number 10 (5 x 2 = 10).

Similarly, if you have a fraction like 1/4, you can undo the division operation by multiplying the fraction by its inverse, which in this case would be 4/1, resulting in 1 (1/4 x 4/1 = 1).

In general, the inverse operation of division is multiplication, and vice versa.
