Alan finished his homework in 1 1/2 hours. It took Jimmy 3/4 of an hour longer than Alan to finish his homework. How long did it take Jimmy to finish his homework?​

Answer:

jimmy took 2 1/4 hours

Step-by-step explanation:

just add both fractions

(3/2) + (3/4) = 9/4 = 2 1/4 hours

Step-by-step explanation:

We need to add 3/4 of an hour to Alan's time.

Let's put Alan's time into a pure fraction.

[tex]1\frac{1}{2} = \frac{2}{2}\frac{1}{2} = \frac{3}{2}[/tex]

Now we can add 3/4 to 3/2.

First, we need to find a common denominator (the bottom number).

4 and 2 is easy. The common denominator is 4. So let's solve it.

[tex]\frac{3}{2} * \frac{2}{2} = \frac{6}{4}[/tex]

[tex]\frac{6}{4} + \frac{3}{4} = \frac{6+3}{4}[/tex]
