Question

From a rope of 11 m long two pieces of lrngths 13/ 5 metre and 33/ 10 metre are cut off what is the length of the remaining rope

Answer 1

First of all make these fractions in decimal form i.e., 
13/5 = 2.6 m and 33/10 =3.3 m.

Now, to find remaining length of the rope add the length of cutting pieces and subtract from total length i.e.,

⇒ 11 - (2.6 + 3.3)
= 11.0 - 5.9
= 5.1 m
