Answer:

Explanation:

Call the movie length m

3/4 m = 1 1/2 hours

3/4 m = 3/2 hours

This is easier to do by decimals

3/4 = 0.75

3/2 = 1.5

0.75 m = 1.5 Divide by 0.75

0.75/0.75 m = 1.5/0.75

m = 2

If it must be done using fractions then this is how it works.

3/4 m = 3/2


(3*m)/(4)=(3)/(2)\\m=((3)/(2) )/((3)/(4) )


m= (3)/(2)*(4)/(3)\\\text{The threes cancel out. So does 2 into 4}

You get 2 just as you did before.
