Ratios that name the same comparison, is what?
-
Proportion
-
Rate
-
Cross product
-
Equivalent ratio
-
Unit rate
Correct Answer
A. Equivalent ratioExplanation
Equivalent ratios are ratios that name the same comparison. They have the same value but may be expressed in different ways. For example, the ratios 2:4 and 1:2 are equivalent because they represent the same comparison of 2 to 4. Therefore, the correct answer is equivalent ratio.Rate this question:

-
Proportion
-
Rate
-
Cross product
-
Equivalent Ratio
-
Unit rate
Correct Answer
A. Unit rateExplanation
A unit rate is the rate in which the second quantity in the comparison is one unit.

Susan found a bag of 20 golf balls at a garage sale and bought the bag for 75 cents. Express the ratio of cost to the number of balls in lowest terms.
-
20:75
-
75:20
-
4:15
-
15:4
Correct Answer
A. 15:4Explanation
The ratio of the cost to the number of balls can be found by dividing the cost by the number of balls. In this case, the cost is 75 cents and the number of balls is 20. Dividing 75 by 20 gives us 3.75. To express this ratio in lowest terms, we can multiply both sides by 4 to get 15:4.Rate this question:

A gardening magazine suggested that a good mix for a flower bed is 20 pails of clay dirt, 15 pails of sand, and 5 pails of manure. Express this in lowest terms.
-
20:15:5
-
10:7:3
-
4:3:1
-
4:3:2
Correct Answer
A. 4:3:1Explanation
The ratio of 20 pails of clay dirt, 15 pails of sand, and 5 pails of manure can be expressed in lowest terms as 4:3:1. This means that for every 4 pails of clay dirt, there are 3 pails of sand and 1 pail of manure in the flower bed mix.Rate this question:

A stackable CD rack holds 25 CDs and costs $4. Charlie has a collection of 150 CDs. How much will it cost him to buy enough racks to hold all of his CDs?
-
$4
-
$24
-
$25
-
$150
Correct Answer
A. $24Explanation
To find the cost of buying enough racks to hold all of his CDs, we need to divide the total number of CDs by the capacity of each rack. In this case, Charlie has 150 CDs and each rack can hold 25 CDs. Therefore, he will need 6 racks (150 CDs / 25 CDs per rack). Since each rack costs $4, the total cost of buying enough racks will be $24 (6 racks * $4 per rack).Rate this question:
