Question

Curtis threw 15 darts at a dartboard. 40% of his darts hit the bull's-eye. How many darts did not hit the bull's-eye?

Answer 1

Number of darts that hit the bull's eye = 15 x 40/100 = 6
Number of darts that did not hit the bull's eye = 15 - 6 = 9

Answer 2

Answer:

Equivalent ratio states that the two ratios are express the same relationship between numbers

As per the given statement: Curtis threw 15 darts at a dashboard.

40% of his darts hit the bull's eye

then;

60 % of his darts did not hit the bull's eyes.

By definition of equivalent ratio;

$\frac{x}{15} = \frac{60}{100}$

Multiply both sides by 15 we have;

$x = \frac{60}{100} \times 15 = \frac{60 \times 15}{100} =\frac{900}{100} = 9$

Therefore, 9 darts did not hit the bull's-eye.
