### Example Question #1 : Ratio And Proportion

Determine the ratio of 6 to 36.

**Possible Answers:**

**Correct answer:**

Ratios represent how one number is related to another. These steps will help you determine the ratio of the numbers shown:

1) Divide both terms of the ratio by the GCF (greatest common factor). In this case, the GCF is 6 because 6 is the greatest number that goes into both numbers evenly.

2) Show the ratio with a colon : and remember to keep the numbers in the same order!

Therefore, the ratio of 6 to 36 is .

### Example Question #1 : Ratio And Proportion

Determine the ratio of 12 to 32.

**Possible Answers:**

**Correct answer:**

Ratios represent how one number is related to another. These steps will help you determine the ratio of the numbers shown:

1) Divide both terms of the ratio by the GCF (greatest common factor). In this case, the GCF is 4 because 4 is the greatest number that goes into both numbers evenly.

2) Show the ratio with a colon : and remember to keep the numbers in the same order!

Therefore, the ratio of 12 to 32 is .

### Example Question #1 : Ratio And Proportion

Riley gives Maddie marbles, then gives Carl marbles. He repeats this process several times.

At the end of this process, Maddie has marbles. How many marbles does Carl have?

**Possible Answers:**

marbles

marbles

marbles

marbles

marbles

**Correct answer:**

marbles

Divide the number of marbles Maddie has by the number she received per turn to find the number of times the process occurred.

, so the process occurred times.

Set up a ratio of the number of marbles given to Maddie to the number of marbles given to Carl on each turn. This ratio would be .

We can find the number of marbles Carl has by multiplying the number of times the process occurred by the number of marbles he received each turn.

marbles.

### Example Question #1 : How To Find A Ratio

Which ratio is "20 to 60" written in simplest form?

**Possible Answers:**

**Correct answer:**

1) Divide both terms of the ratio by the greatest common factor. In this case, the greatest common factor is 20, because 20 is the largest number that goes into both numbers evenly.

2) Show the ratio with a colon (:). Remember to keep the numbers in the correct order!

Therefore, 20 to 60 is equivalent to 1 : 3.

### Example Question #1 : Ratio And Proportion

Determine the ratio of 12 to 48 in simplest form.

**Possible Answers:**

**Correct answer:**

1) Divide both terms of the ratio by the greatest common factor. In this case, the greatest common factor is 12, because 12 is the greatest number that goes into both numbers evenly.

2) Show the ratio with a colon (:), and remember to keep the numbers in the correct order.

Therefore, the ratio of 12 to 48 is .

### Example Question #2 : Ratio And Proportion

Simplify the ratio: 400 students to 25 teachers

**Possible Answers:**

**Correct answer:**

A ratio can be simplified by dividing both numbers by their greatest common factor. Since 400 is divisible by 25, the GCF is 25.

The ratio, simplified, is .

### Example Question #2 : Ratio And Proportion

If there are 6 girls in a class and 12 boys in a class, what is the ratio of girls to boys in the class, in simplest form?

**Possible Answers:**

**Correct answer:**

To find a ratio, divide the two numbers given until they are reduced to their lowest common factor, then put them into a ratio with a colon in between. Remember to order them in the way the question is asked!

6 (girls) and 12 (boys) can both be divided by 6:

For every girl, there are 2 boys in the class. Therefore, the ratio is .

### Example Question #1 : Ratio And Proportion

Which of the following is in a simplified form?

**Possible Answers:**

**Correct answer:**

In order to reduce to its simpler form, the key is to divide each side by the same number. Dividing each side by 4 gives us a reduced ratio of , which is the correct answer.

### Example Question #1 : How To Find A Ratio

Determine the ratio of to .

**Possible Answers:**

**Correct answer:**

Ratios represent how one number is related to another. These steps will help you determine the ratio of the numbers shown:

) Divide both terms of the ratio by the GCF (greatest common factor). In this case, the GCF is because is the greatest number that goes into both numbers evenly.

) Show the ratio with a colon : and remember to keep the numbers in the same order!

Therefore, the ratio of to is .

### Example Question #1 : Ratio And Proportion

A car with a tank that holds gallons of gas gets miles to the gallon. If the car's gas gauge reads that the tank is three-fourths full, how many miles can it travel before it needs to be refueled?

**Possible Answers:**

**Correct answer:**

Multiply miles per gallon by gallons to get the distance the car can travel on a full tank:

miles.

Multiply this by three-fourths to get the distance it can travel on three-fourths of a tank.
