Answer:
64
Step-by-step explanation:
Looking at the number 63.62, you see that 6 comes immediately after the decimal point.
Now if the number after the decimal point is more than 5 we round up by adding one to the number just before the decimal point which is 3 in this case.
Assuming the number after the decimal point was less than 5 we would round down adding nothing to the number just before the decimal point.
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. (<em>Note: not the regular ones) </em>as a percentage.
This will be (18/25) X 100 = 72%
Therefore, 72 percent of the total houses are small
