Question

Arrange the numbers with the help of a number line:

$16.3,17.7\text{and}17.12$

• A. $16.3<17.12<17.7$
• B. $16.3<17.7<17.12$
• C. $17.7<17.12<16.3$

Answer 1

The correct option is A $16.3<17.12<17.7$

Let's mark the numbers on the number line one by one.

16.3

16.3 = 16.30

16.30 is more than 16 but less than 17.

$\therefore$ 16.30 will lie left to 17.


17.7

17.7 = 17.70

17.7 is less than 18 but greater than 17.5.

$\therefore$ 17.7 will lie right of 17.5.


17.12

17.12 is less than 17.50 but greater than 17.

$\therefore$ 17.12 will lie in between 17 and 17.5.


Hence, $16.3<17.12<17.7$
