Question

$\text{The sum of 350 mm and 135 cm is}$ $\text{m.}$

• A. $1.7$
• B. $1.5$
• C. $1.9$
• D. $1.3$

Answer 1

The correct option is A $1.7$

To add the given numbers, we have to make the units same.

$\text{1 mm =}\frac{1}{10}\text{cm}$

$\text{350 mm =}\frac{350}{10}\text{= 35 cm}$

Now, $\text{35 cm + 135 cm = 170 cm}$

Now, $\text{1 cm =}\frac{1}{100}\text{m}$

Now, $\text{170 cm =}\frac{170}{100}\text{m}$
$\text{= 1.7 m}$
