Question

Gisla is $1$ m and $70$ cm tall. In her biodata, she must include her height. If heights can only be filled in fractions, what must she write in the height(in m) column?

• A. $\frac{17}{10}$
• B. $\frac{17}{100}$
• C. None of the above

Answer 1

The correct option is A $\frac{17}{10}$

Note:
$1$ m $=100$ cm
$1$ cm $=\frac{1}{100}$ m
$=0.01$ m
So,
$70$ cm $=\frac{70}{100}$
$=0.70$ m
Gisla's height $1+0.7=1.7$ m
Converting Gisla's height $1.7$ m into fraction.
As,
$\Rightarrow 1.7=\frac{1.7\times 10}{10}$
$=\frac{17}{10}$

Answer:
Gisla will fill her height as $\frac{17}{10}$m.
