Make the ratios equal. 9:25 = 36:?
satela [25.4K]

The equivalent ratio of 9:25 is 36:100.

Ratio expresses the degree of proportionality between two or more numbers. It expresses the number of times one number is contained in another number.  

In order to make the ratios equal, the relationship that exists between 9 and 36 has to be determined. 36 is a multiple of 9. It is 9 multiplied by 4. So, in order to make the ratios equal, multiply, 25 by 4.

25 x 4 = 100

One pipe can fill a pool in 9 hours. Another pipe can fill the pool in 6 hours. How long would it take them to fill the pool if
kow [346]

Answer:

3.6 hours or 3 hours and 36 minutes.

Step-by-step explanation:

If the first pipe can fill the pool in 9 hours that means that in 1 hour it fills \frac{1}{9} of the pool, we use the same logic for the second pipe and conclude that in 1 hour it feels up \frac{1}{6} of the pool. If both were to fill the pool together that means that in 1 hour they would fill...

\frac{1}{9} +\frac{1}{6} = \frac{5}{18} of the pool in 1 hour.

Now to find how many hours it will take divide the pool by the speed with which it is getting filled.

1 / \frac{5}{18} = 3.6 hours

3.6 hours in other words is 3 hours and 36 minutes.
