Answer:
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 answer:
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

To write an expression, you need operators such as -,+,or *. You will also require numbers, or in algebraic cases, variables. Two expressions that equal each other are considered <em>equations</em>. Know that <em>expressions</em> do not have equal signs, this is what separates them from a standard <em>equation</em>.
Some examples of expressions:
2 + 5
3 - 2
10 + 4
Some examples of equations
2 + 3 = 4 + 1
9 - 3 = 5 +1
2 * 10 = 5 + 15
