The fraction of magazines that were delivered to families who were at home is 0.4 if total number of families are 25 out of which 10 were at home and rest are away.
Total number of families = 25
Families at home = 10
So the ratio of the required families
= Families at home/total number of families
= 10/25
= 2/5
To convert the fraction into decimal form, we have to divide and we get
= 0.4
Hence, the number of families in decimal to which magazines got delivered are 0.4

Proportion is the correct answer.
It's a bit hard to do a model on here, but I'll try to represent it. Note that the "a"s are the shaded parts and the "b"s are the non-shaded parts.
a a a
a a a
a a a
b b b
b b b
There are 9/15 shaded.
Given:
In triangle ABC, Q is the centroid and FQ=9.
To find:
The length of FC and QC.
Solution:
We know that, centroid is the intersection point of medians of a triangle and medians divide teach other in 2:1. So, centroid divided each median in 2:1.
CF is a median and Q is the centroid. So,
Let the length of QC and FQ are 2x and x respectively.
We have, FQ=9.
Now,
And,
Therefore, the length of FC is 27 units and length of QC is 18 units.
