Explanation: I am sure you missed an extra 10 in your problem. There are supposed to be four 10's (Well at least in my problem). The rest you know, the answer are stated for the set of data: 10, 1, 10, 15, 1, 7, 10, 10, 1, 6, 13.
The problem above is related to the topic on "Equivalent Ratios." The missing term above is <em>"the number of miles that the vehicle can travel per gallon of gasoline."</em> In order to find this term, you have to use the "cross products."
Let n be the missing term.
/ =
/ =
x n = x 1 gallon
n = ÷
n = x
n = 12 miles
Therefore, the vehicle can travel 12 miles per gallon of gasoline.
504/9= 56 504/8= 63 504/7= 72 504/6= 84 ..... we can continue the pattern. However, we know that 50 is the product of 8 and 7, so we can use that number
