SOL Review: Computation & Estimation

What equation is being modeled?

• 3/5 · 1/4 = 3/20

• 3/4 · 1/5 = 6/20

• 6/20 · 3/20 = 2/9

• 9/20 · 2/20 = 3/20

The value of 3 1/2 · 1/8 is ______.

• greater than 3 1/2 because the second factor is less than 1.

• less than 3 1/2 because the second factor is less than 1.

• greater than 3 1/2 because the product is always larger than the two factors.

• less than 3 1/2 because you have to use keep, change, reciprocate to solve.

The value of 3 1/2 ÷ 1/8 is ______.

• greater than 3 1/2 because the divisor is less than 1.

• less than 3 1/2 because the divisor is less than 1.

• less than 3 1/2 because the quotient is always smaller than the dividend.

• greater than 3 1/2 because you solve 1/2 ÷ 1/8 first.

Which numbers can be placed in the blank to create a negative value? (choose all correct answers).

-4 - ____

• -7

• -3

• 4

• 8

|-21| ÷ (-3)

-9 · (-7)

7 + (-11)

7 - (-11)

What equation is being modeled?

• 7 ÷ (-4) = 3

• 7 - (-4) = 11

• -4 + (-7) = -11

• -4 + 7 = 3
