Answer:
72 percent of the total houses are small
Step-by-step explanation:
The first step is to know the total apartments from the ratio: This is got by adding 18 + 7 = 25
The ratio of small apartments to regular ones is 18:7
To get the percentage that is small, we have to express the number of small houses when compared to the total available apartments. (Note: not the regular ones) as a percentage.
This will be (18/25) X 100 = 72%
Therefore, 72 percent of the total houses are small
