9) Estimate each product. Draw a bar diagram to help: 3/4 x 23
3/4 x 24 = 18 OR 3/4 x 20 = 15, so 3/4 x 23 is ABOUT 15 or 18.
10) Estimate each product. Draw a bar diagram to help: 1/5 x 22
1/5 x 20 = 4, so 1/5 x 22 is ABOUT 4.
11) Multiply. Write the product in simplest form: 1/3 x 21
1/3 x 21 = 21/3 which is 7.
12) Multiply. Write the product in simplest form: 26 x 1/2
26 x 1/2 = 26/2 which is 13.
13) Multiply. Write the product in simplest form: 1/5 x 3/8
1/5 x 3/8 = 3/40
14) Multiply. Write the product in simplest form: 1/2 x 7/8
1/2 x 7/8 = 7/16
15) Multiply. Write the product in simplest form: 3u1/4 x 3/5
13/4 x 3/5 = 39/20 or 1u19/20
16) Multiply. Write the product in simplest form: 1u1/8 x 3u2/3
9/8 x 11/3 = 99/24 = 33/8 or 4u1/8
