Mathematics

Answer:

-1

Step-by-step explanation:

The given expression is:

-\frac{2}{3}\div \frac{4}{6}

We multiply by the reciprocal to get:

-\frac{2}{3}\times \frac{6}{4}

We factor so that we can cancel easily:

-\frac{2}{3}\times \frac{3\times 2}{2\times 2}

Cancel the common factors to get:

-\frac{1}1}\times \frac{1\times 2}{1\times 2}

This simplifies to:

-1

Find the sale price of each item. Round to two decimal places when necessary.
Grace [21]

Answer:

8. $35.10

9. $59.63

10. $13.43

11. $70

12. Take the percent you pay (100-the discount) as a decimal and multiply it by the regular price.

Step-by-step explanation:

For finding the price we pay during a sale, we focus on the percent we pay. If 22% off is the sale, then we spend 78% or 100-22-78. We use this percent byb  multiplying the price with a decimal. We convert percents into decimals by dividing the percent number by 100. For example, 78% divided by 100 becomes 0.78.

8. Percent off is 22%. We pay 78%=0.78.

45(0.78)=$35.10

9. Percent off is 33%. We pay 67%=0.67.

89(0.67)=$59.63

10. Percent off is 44%. We pay 56%=0.56.

23.99(0.56)=$13.43

11. Percent off is 75%. We pay 25%=0.25.

279.99(0.25)=$70

12. See explanation above.
