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

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:

[tex]14 - 8 = 6[/tex]

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

[tex] \frac{6}{14} [/tex]

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:

[tex]\frac{6}{14} = \frac{x}{100} [/tex]

The answer is B.
