Question

On the above number line, 'y' represents

• A. 0.06
• B. 0.85
• C. 0.86
• D. 0.88

Answer 1

Answer: (C)

0.86

The given decimals are $0.8$ and $0.9$

$\Rightarrow$ Difference between decimals $=0.9-0.8=0.1$

Now line is divided in $5$ equal segments.

Value of each segment is:

$\Rightarrow$ $0.1÷5=\frac{0.1}{5}=0.02$

$y$ is placed at $3rd$ segment from $0.8$.

$\therefore$ Value of $y$$=0.8+0.02+0.02+0.02=0.86$
