The value of n is 24.
18⁄24 = 21⁄28
Step-by-step explanation:
Finding the Missing Term in a Proportion
A proportion refers to a statement of equality between two ratios. Cross multiplication method is used to find the missing term in a proportion. It is also used to determine whether the ratios are equal and form a proportion. The cross products should be equal to tell that the ratios are proportional.
Below are the steps to follow together with the solution of the given proportion above:
1. Write the proportion.
18/n = 21/28
2. Cross multiply.
21n = 18(28)
21n = 504
3. Divide to find the missing term (n).
21n/21 = 504/21
n = 24
Therefore, the missing term is 24. Plug the value of n in the proportion to get 18⁄24 = 21⁄28.
4. Checking
Let us check if the answer is correct.
18⁄24 = 21⁄28
24(21) = 18(28)
504 = 504 ✔
