Question

A) 12
B) 15
C) 10
D) 18

Answer 1

Option B). To find the number of seniors likely to live in an apartment, divide the total number of seniors by the ratio of seniors living in an apartment to seniors not living in an apartment. Multiply the result by the number of seniors living in an apartment in each group.

Step-by-step explanation:

To find the number of seniors likely to live in an apartment, we can use the ratio 6 out of 8.

The ratio 6 out of 8 can be simplified to 3 out of 4.

So, if 3 out of 4 seniors live in an apartment, then for every 4 seniors, 3 will live in an apartment.

There are 20 seniors in total, so we can divide 20 by 4 to find the number of groups of 4 seniors.

20 divided by 4 equals 5.

Therefore, there will be 5 groups of 4 seniors, and since for every group of 4 seniors, 3 will live in an apartment, we can multiply 5 by 3 to find the total number of seniors likely to live in an apartment.

5 multiplied by 3 equals 15.

Therefore, 15 seniors are likely to live in an apartment.
