The ratio of ducks to chickens at mr. mc donald's farm is 1 to 3. there are 12 chickens on the farm. what is the total number of ducks and chickens on mr. donalds' farm?

4 ducks

12 chickens

Step-by-step explanation:

Ducks to Chicken (ducks : chicken) ratio

= 1 : 3

Ducks to Chicken ratio, if chickens = 12

= ? : 12

1 : 3 = ? : 12

Find the scale factor of the ratios by dividing the number of chickens to the ratio of chickens.

12 ÷ 3 = 4

To find the number of ducks, multiply the ratio of ducks by the scale factor.

1 X 4 = 4

Therefore, there are 4 ducks and 12 chickens on the farm.

Ratios can also be written like fractions. Use this to check the

1/3 = 4/12

4/12 can be reduced by dividing both the top and the bottom by 4.

4/4 = 1  Same as original ratio top

12/4 = 3  Same as original ratio bottom
