Question

Amy won 8 out of the 14 rounds of cards that she played. Which proportion can she use to find x, the percent of rounds that she lost?

A) 8/14=x/100
B) 6/14=x/100
C) 6/100=x/14
D) 14/6=x/100

Answer 1

b) 6/14=x100

Explanation:

Set up the proportion to be number lost / total = x /100 so the correct proportion is 6 /14 = x /100

.

Answer 2

Amy played a total of 14 rounds and won 8. Subtract the total amount of rounds by the amount she won to find the amount she lost:


`14 - 8 = 6`

Amy lost 6 out of 14 rounds she played. This can be set up as a fraction:


`(6)/(14)`

The numerator represents the rounds lost, and the denominator represents the total rounds played. To convert this into a percent, we can set up the following proportion:


`(6)/(14) = (x)/(100)`

The answer is B.
