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.
11) Multiply. Write the product in simplest form: 1/3 x 21
1/3 x 21 = 21/3 which is 7.
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.
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
4) The process of resizing a number when you multiply by a fraction that is greater than or less than 1.
Scaling
15) Multiply. Write the product in simplest form: 3u1/4 x 3/5
13/4 x 3/5 = 39/20 or 1u19/20
1) The result of a division problem
Quotient
5) Operations that undo each other, such as multiplication and division.
Inverse Operations
7) A number that has a whole number part and a fraction part.
Mixed Number
18) Find each quotient. Use the model. Check with multiplication: 1/3 divided by 5y
1/15 [1/15 x 5 = 5/15 or 1/3]
2) The number that divides the dividend.
Divisor
13) Multiply. Write the product in simplest form: 1/5 x 3/8
1/5 x 3/8 = 3/40
