A family uses 68.6 gallons of water per week while they are camping. What is the unit rate of water they use per day?

• 9.8

• 8.1

• 15.2

• 5.6

Answer explanation

The unit rate of water used per day is 9.8 gallons per day. This is calculated by dividing the total amount of water used per week (68.6 gallons) by the number of days in a week (7 days).

The reason you can find the answer this way is because there are 7 days in a week and by asking the "unit rate for a day" they are asking you to find the amount used in one day.

Eight machines polish 72 tables in one hour. What is the ratio of the number of machines to the number of tables that can be polished in one hour?

• 1 : 8

• 1 : 9

• 8 : 9

• 9 : 8

Answer explanation

Set up te ratio machines to tabes (8 to 72) as a fraction and then reduce it to it's simplest form. To do that, divide both numbers by the greatest common factor (in this case 8). The result (1 to 9) should then be re-written with a colon to match the answer choices.

What is the ratio of shaded boxes to unshaded boxes as shown in the grid in the picture? Remember to simplify the ratio if needed.

Answer explanation

Set up the ratio in the same order as the way the question set it up. It asks for the ratio of shaded to not shaded, so you'll write the ratio that way by counting the number of shaded boxes and writing that number followed by a colon (:). Finally count the number of unshaded boxes and write that number after the colon.
