Que in english this is what
We have some rules about that:
1. n is divisible by 2, so it has to end by an even number such as 0, 2, 4, 6, 8.
2. n is divisible by 3, so the sum of its digits is a number divisible by 3
3. <span>n is divisible by 5, so it has to end by 0 or 5.
4. n is divisible by 4, so its two last digits forming a number divisible by 4 like 212, 3<span>04
</span>5. </span><span>n is divisible by 9, so the sum of its digits is a number divisible by 9
6. </span> <span>n is divisible by 10, so it has to end by 0.
and there are some other rules like if n is divisible by 2 and 3, so it is divisible by 6</span>

A median of a triangle is a segment joining any vertex of the triangle to the midpoint of the opposite side. All triangles have three medians, which, when drawn, will intersect at one point in the interior of the triangle called the centroid. The centroid of a triangle divides the medians into a 2:1 ratio.
Answer:
The problem is with the arrangement of the ratios
PQ is the whole line but PR is a part of it only so you need QR to the ratio of PR
