Answer:
c.1
Step-by-step explanation:
5: 15 x:3
a:b c:d The ratios have to stay in proportion. So if we multiply a and b by a certain number they will equal c and d. We just don't know what that number is yet. Call it something.
a* something = c and b* something =d
5 * something = x
15* something = 3
Solve for the unknown number we are multiplying by
Divide each side by 15
15/15 * something =3/15
something = 1/5
Now that we know what we are multiplying by, we can solve for x
So 5 * something = x
5* 1/5 = x
1 =x
If the average of six numbers is 18, there sum may be calculated by multiplying this average with 6 which gives us, 108. Three of these numbers have the average of 15. By the same principle, the sum of these numbers is 45. The sum of the remaining numbers in the set may be obtained by subtracting the sum of the three from the total, 108 - 45 which is equal to 63. Thus, the answer is 63.
Answer:
