An iron rod is 1.2 m long. A stick is 40 cm long. A pole is 0.8 m long. Find the ratio of the length of the pole to the length of the stick to the length of the iron rod. Express your answer in its simplest form.

Answer 1

First, convert all lengths to the same unit (meters):

Iron rod: 1.2 m
Stick: 40 cm = 0.4 m
Pole: 0.8 m

Now, we can find the ratio:

Pole : Stick : Iron rod
0.8 : 0.4 : 1.2

To simplify the ratio, divide all lengths by the smallest value, which is 0.4:

0.8 ÷ 0.4 = 2
0.4 ÷ 0.4 = 1
1.2 ÷ 0.4 = 3

So, the ratio of the length of the pole to the length of the stick to the length of the iron rod is:

2 : 1 : 3
