simplify and state the restrictions on the variables.

Question

4/mn * m/2

Answer 1

The variables m or n cannot be equal to 0. (You cannot have a 0 in the denominator.)

4/mn * m/2 = 4m/2mn

Reduce the fraction. (Hint: common factors in the numerator and denominator are 2 and m.)

I hope this will help.
