Question

The stop signal is placed 7/5 km after the signal warning board. What is the correct position of the stop signal on the number line?

• A. Between 0 and 1
• B. Between 1 and 2
• C. Between 0 and -1
• D. Between 0 and -2

Answer 1

The correct option is B Between 1 and 2

$\text{Since the stop signal lies at position}\frac{7}{5}$
after the warning sign board which is at '0', the signal lies on the right of 0 on the number line.

$\text{Converting}\frac{7}{5}\text{to mixed fraction, we}$ $\text{have}\frac{7}{5}=1\frac{2}{5}$

Hence, it lies between 1 and 2.

Let’s assume each division on the number line is 1 km.

$\text{To plot}\frac{2}{5}\text{each unit needs to be divided into}$ 5 parts and it needs to be placed on the second part out of the 5 parts as shown below:


Hence, second option is the correct answer.
