Question

A length of rope is divided into two pieces in the ratio 2:5 If the longer

piece is 120 m, what is the length of the shorter piece? (SHOW WORKING)​

Answer 1

The answer is

34.3 m

Explanation:

To find the length of the shorter piece we must first find the total parts

That's

2 + 5 = 7

Looking at the ratio above we can see that 2 is the smaller part which makes it the shorter piece

Now divide 2 by the total parts and multiply by 120

That's

`(2)/(7) * 120 \\ = (240)/(7) \\ = 34.285714`

We have the final answer as

34.3 m

Hope this helps you
