Question

The length of three boards added together is 7.2 meters. The second board is twice the length of the first. The third board is three times the length of the first. What is the length of the three boards?

Answer 1

Board 1 = 1.2m

Board 2 = 2.4m

Board 3 = 3.6m

Explanation:

Board 1 = x

Board 2 = 2x

Board 3 = 3x
x + 2x + 3x = 6x

7.2 /6 = 1.2

Board 1 = 1.2

Board 2 = 2 (1.2) = 2.4

Board 3 = 3 (1.2) = 3.6
