What is the difference between finding a point one-fourth of the way from a to b and finding a point one fourth of the way from b to a? what
is the difference between partitioning a line segment according to a part-to-part ratio, and partitioning a line segment according to a part-to-
whole ratio?

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
