What do you do if you have a fraction saying ... 1 1/2 x 2 1/3

3 1/2.

Step-by-step explanation:

First you convert to an improper fraction with the top part geing greater than the bottom, as follows:

1 1/2 = (1*2 + 1) / 2 = 3/2.

2 1/3 = (2*3 + 1) / 3 = 7/3.

When multiply these you just multiply the top parts and the bottom and, if necessary, simplify.

3/2 * 7/3 = 3*7 / 2*3

= 21/6 Now simplifying:

= 7/2

Now we can convert this improper fraction to standard form:

Dividing 7 by 2 gives 3 with remainder 1 so we have

7/2 = 3 1/2. (answer).
