Question

At batting practice Alexis hit 8 balls out of 15 into the outfield. Which equation below can be used to determine the percentage of balls it into the outfield?A. 15/8 = x/100B. 15/100 = x/8C. 8x = (100)(15)D. 15/8 = 100/x

Answer 1

EXPLANATION

Since Alexis hit, the appropriate relationship should consider a division between the number of balls Alexis hit and the total.

Dividing them gives the following expression:

$\frac{8}{15}$

Now, in order to represent as a percentage, we must multiply this fraction by 100:

$\frac{8}{15}*100$

Equaling the fraction to x, assuming that x represents the computed percentage:

$\frac{8}{15}*100=x$

Dividing both sides by 100:

$\frac{8}{15}=\frac{x}{100}$

Reversing the fractions:

$\frac{15}{8}=\frac{100}{x}$

In conclusion, the equation that gives the appropriate relationship is OPTION D
