Vonna scored 35 goals at soccer practice. Her ratio of goals to misses was 5:8. How many times did she miss?

Digiron [165]

<u>Answer:</u> She misses 56 times at a soccer practice.

<u>Step-by-step explanation:</u>

Let the goals she misses be 'x'.

According to the question:

$5:8::35:x$

These two ratios follow direct relationship, so:

$\frac{5}{8}=\frac{35}{x}\\\\5x=35\times 8\\\\x=\frac{280}{5}\\\\x=56$

Hence, Vonna misses 56 times at a soccer practice.

A basketball player makes 4 out of 20 free throws. What is his shooting percentage?

DiKsa [7]

We can convert that into a fraction of 100 for the percentage.

4/20= 20/100

(multiply both by 5)

So, the basketball player makes 20% of the throws.
