What is 72 x 1/4?

I have no clue!

18

Step-by-step explanation:

Honestly you can just use a calculator for this.

But if you want to know how to actually do it, multiplying something by a fraction is just dividing it by its reciprocal (just flipping the numerator and the denominator).

Therefore ...

72/4 is 18, 72 x 1/4 = 18

without a calculator u can solve by divideing 72 by 4

answer is 18
