Question

Two pipes of length 1.5 m and 1.2 m are to be cut into equal pieces without leaving any extra length of pipes. The greatest length of the pipe pieces of same size which can be cut from these two lengths will be

A) 0.13 m B) 0.4 m C) 0.3 m D) 0.41 m

Answer 1

Step-by-step explanation:

The greatest length of pipes of same size will be HCF of 1.5 m and 1.2 m.

So HCF of 15 and 12 is 3, then HCF of 1.5 and 1.2 is 0.3 m
