Question

There are a total of 32 bikes. The kids ratio of blue bikes to white is 3 to 5. How many bikes are white?

Answer 1

Is that backwards ratios? We r learning about ratios right now soo I’m still confused on that. Sry

Answer 2

Answer:

20 white bikes

Step-by-step explanation:

The kids ratio of blue bikes to white is 3 to 5.

The sum of ratio is 3+5=8

so, out of 8 bikes , 5 bikes are blue

Now we need to find out how many bikes are white out of total 32 bikes

Let the number of white bikes is x

We make proportion

$\frac{ratio-White}{ratio-total} = \frac{White}{total}$

$\frac{5}{8} = \frac{x}{32}$

cross multiply it

5 * 32 = 8*x

160 = 8x

Divide both sides by 8

x= 20

So number of white bikes = 20
