At the local fire station they have different lengths of fire hose. the shortest is half the length of the middlesized 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.
