At the local fire station they have different lengths of fire hose. the shortest is half the length of the middle-sized one, and one fifth of the length of the longest one. if i connect the three different hose lengths together i make a hose 120m long. how long is the shortest hose? how long is the middle hose? how long is the longest hose? please show workings. thanks

Let x = length of smallest hose

x + 2x + 5x = 120

Solve for x.

think of it this way

trial and error

x+ 2x + 5x = 120.

think of numbers that could add up this amount.

like 15, 30, 75.

easy.
