PLS HELP!!

Answer 1

Answer B is correct

Explanation:

`\sf1 (1)/(2) * 3 (1)/(2) \\`

First, make these two fractions as improper fractions.

`(3)/(2) * (7)/(2) \\`

Multiply.

`(21)/(4) \\`

Now write the answer as a mixed number.

`(21)/(4) \rightarrow5 (1)/(4) \\`

Answer 2

5 1/4

Explanation:

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

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

1 1/2 * 3 1/2 =

3/2 * 7/2 = 21 /4

Now changing back to a mixed number

21 /4 4 goes into 21 5 times (20) with 1 left over

5 1/4
