Answer: 1/243

Step-by-step explanation: To simplify the problem shown, our first step is to convert the decimal in the exponent, -2.5, to a fraction.

-2.5 is the same thing as -2 and 1/2 so we have 9^-2 and 1/2 and -2 and 1/2 is the same thing as -5/2 so we have 9^-5/2.

Hello!

1. To convert minutes to hours, we must multiply the number of minutes by 60, because that is how many minutes there are in an hour.

2. 1 pint = 16 ounces

16 × 8 = 128

Fernando bought 128 fluid ounces of milk.

3. 1 quart = 0.25 gallons

0.25 × 8 = 2

2 gallons are equivalent to 8 quarts.


4. Because when you divide 25 by 8, the result is greater than 3.

5. By dividing 6,400 by 2,000, because that is how you will find the exact equivalent of 6,400 pounds in tons.

7. 1 pound = 16 ounces

16 × 80 = 1,280

1,280 ounces is equivalent to 80 pounds.

9.

The missing value in the table is 918, because:

1 yard = 3 feet

3 × 306 = 918

306 yards = 918 feet
