Answer:

Step-by-step 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

[tex]\frac{3*m}{4}=\frac{3}{2}\\m=\frac{\frac{3}{2} }{\frac{3}{4} }[/tex]

[tex]m= \frac{3}{2}*\frac{4}{3}\\\text{The threes cancel out. So does 2 into 4}[/tex]

You get 2 just as you did before.
