5/6

Explanation:

Step 1: You have to Multiply the 3 and the 2 together and then add the 1 and that would all be over 3. Then you get

2 1/3 = (2 xx 3 + 1)/3 = 7/3

Step 2: You do the same thing which is 2 times 1 and then add 1 and that would be all over 2. Then you get

1 1/2 = (1 xx 2 + 1)/2 = 3/2

Step 3: Combine together as

7/3 - 3/2

Next, you have to have a common denominator of 6. 7/3 times 2 both top and bottom. Then 3/2 is going to be times 3 both top and bottom.

7/3 xx 2/2 = (7 xx 2)/(3 xx 2)

3/2 xx 3/3 = (3 xx 3)/(2 xx 3)

Next, multiply top and bottom fractions individually, which gets to be

14/6 - 9/6 = (14 - 9)/6 = 5/6

5/6

Explanation:

First, change the mixed fractions into improper fractions by multiplying the whole number by the denominator and then adding the numerator.

2 1/3= (2xx3+1)/3 = 7/3

1 1/2= (1xx2+1)/2 = 3/2

Next, find a common denominator and then multiply the top and the bottom by the same number.

7/3 xx 2/2 = 14/6

3/2 xx 3/3 = 9/6

Subtract the numerators.

14-9= 5

Make sure to keep the denominator.
