Example Question #115 : How To Find A Ratio
There are 50 orange cats and 20 black cats. What is the ratio of black to orange cats?
The number of black cats goes before the colon since this question is asking for the ratio of black to orange cats.
Therefore, there are .
This can be simplified if you divide both numbers by 10. This gives a ratio of .
Example Question #111 : How To Find A Ratio
Find .
If you have to solve a proportion or a ratio, all you have to do is cross-multiply and divide by what is left.
Example Question #781 : Ssat Middle Level Quantitative (Math)
What is the simplest form of the following ratio: 325:50?
In order to determine the simplest form of a ratio, divide both sides of the ratio by a common factor. If we divide each side of this ratio by 5, we get 65:10.
This can still be simplified by dividing by 5 again.
Therefore, the simplest form of the ratio is 13:2.
Example Question #6 : Use Ratio Reasoning To Convert Measurement Units: Ccss.Math.Content.6.Rp.A.3d
A carpenter is making a model house and he buys of crown molding to use as accent pieces. He needs of the molding for the house. How many feet of the material does he need to finish the model?
We can solve this problem using ratios. There are in . We can write this relationship as the following ratio:
We know that the carpenter needs of material to finish the house. We can write this as a ratio using the variable to substitute the amount of feet.
Now, we can solve for by creating a proportion using our two ratios.
Cross multiply and solve for .
Simplify.
Divide both sides by .
Solve.
The carpenter needs of material.
Example Question #2101 : Psat Mathematics
A carpenter is making a model house and he buys of crown moulding to use as accent pieces. He needs of the moulding for the house. How many additional feet of the material will he need to purchase to finish the model?
We can solve this problem using ratios. There are in . We can write this relationship as the following ratio:
We know that the carpenter needs of material to finish the house. We can write this as a ratio using the variable to substitute the amount of feet.
Now, we can solve for by creating a proportion using our two ratios.
Cross multiply and solve for .
Simplify.
Divide both sides by .
Solve.
The carpenter needs of material. Since he already has he will need to purchase more to finish the project.

Example Question #3 : How To Find A Proportion
Read this problem, but do not solve it.
4 out of every 5 dentists surveyed recommend Triton sugarless gum to patients who chew gum. If 2,100 dentists were surveyed, how many dentists recommended Triton?
If we let be the number of dentists who recommended Triton, what proportion statement could be used to solve this problem?
The ratios that are set equal to each other in a proportion statement must compare the same quantities in the same order.
In each ratio, we can put number of dentists who recommended Triton in the numerator, and number of dentists who were surveyed in the denominator.
One ratio is 4 dentists recommending Triton to 5 dentists surveyed (the general ratio): this is .
The other ratio is dentists recommending Triton to 2,100 dentists surveyed (the actual number); this is .
The proportion statement sets these equal:
which is the correct choice.
