Question

There is a telephone wire of length$8m$. It is divided into $10$ equal parts. What is the length of each part in cm? ($1m=100cm$)

• A. 8 cm
• B. 800 cm
• C. 980 cm
• D. 80 cm

Answer 1

The correct option is D 80 cm

Length of the telephone wire $=8m$

• $1m=100cm$
• To get the length in cm, we multiply 8 m with 100 (as 1 m = 100 cm).
• $8\times 100=800cm$
• Thus, there are 800 cm in 8 m.
• Now, 800 cm is divided into 10 equal parts.
• Length of each part $=\frac{800}{10}=80cm$

Hence, C is the correct option.
