Line segment ab has endpoints a(1, 2) and b(5, 3). find the coordinates
of the point that divides the line seament directed from a to b in the ratio
of 1: 3

ratio = 2:3 = 2/5

Distance between the x coordinates: 3

Distance between the y coordinates: 7

x: 3 * 2/5 = 1.2

y: 7 * 2/5 = 2.8

x coordinate of point: 6 - 1.2 = 4.8

y coordinate of point: 1 + 2.8 = 3.8

So the point that divides the segment AB in the ratio of 2:3 is (4.8 , 3.8) or (24/5 , 19/5)

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
