How can you use a reciprocal change a division problem into a multiplication problem?
Division by a number is the same as multiplication by its reciprocal. That is, n / a = n * (1/a) and as you should know, (1/a) is the reciprocal of a.

Why is division simply multiplying the dividend by the reciprocal of the divisor?
That's how division is formally defined in advanced math.
