Question

problems 6 - 7: circle the phrase that makes each statement true.

1. the value of the expression 15·0.75 is...

less than 15
greater than 15

1. the value of the expression 15·1.3 is...

less than 15
greater than 15
problems 8 - 11: determine the missing value in each equation.

1. 32·□ = 4
2. 24·□ = 3
3. 16·□ = 2
4. 8·□ = 1

Explanation:

Step1: Analyze 15 * 0.75

Since 0.75 < 1, when we multiply 15 by a number less than 1, the product will be less than 15. So 15 * 0.75 < 15.

Step2: Analyze 15 * 1.3

Since 1.3 > 1, when we multiply 15 by a number greater than 1, the product will be greater than 15. So 15 * 1.3 > 15.

Step3: Solve 32 * x = 4

We use the formula $x=\frac{4}{32}=\frac{1}{8}=0.125$.

Step4: Solve 24 * x = 3

We use the formula $x = \frac{3}{24}=\frac{1}{8}=0.125$.

Step5: Solve 16 * x = 2

We use the formula $x=\frac{2}{16}=\frac{1}{8}=0.125$.

Step6: Solve 8 * x = 1

We use the formula $x=\frac{1}{8}=0.125$.

Answer:

1. Less than 15
2. Greater than 15
3. 0.125
4. 0.125
5. 0.125
6. 0.125
