Question

The points Q, R, S and T all lie on the same line segment, in that order, such that the ratio of QR : RS : ST is equal to 6 : 2 : 1. If QT = 36, find RT.

Answer 1

Answer: 12

Explanation:

U add the ratios together and get the number 9 meaning there’s 9 total sections. Then u divide the 36 into those 9 segments and get 4 units per segment. It’s asking for RT and to get that u need to add RS and ST which are 3 segments in total (2+1) now 3 segments multiplied by 4 units equals 12 units in total for RT
