$38 c m \equiv 1.246875 \text{ feet" larr" exact value}$

$38 c m \approx 1 \text{foot " 2" inches "61/64ths larr" approximate}$

#### Explanation:

1 mitre is 3 feet 3 inches and 3/8 of an inch

Converting this to decimal

$\frac{3}{8} \text{ inch" = 0.375" inches}$

$3 + \frac{3}{8} \text{ inches "= 3.375" inches}$

But there are 12 inches in a foot so

$3 \frac{3}{8} \text{ "-= 3.375xx1/12 = 0.28125" feet}$

So $\textcolor{b l u e}{\text{1 metre " -=" " 3" feet "3color(white)(.) 3/8" inches" color(blue)(->3.28125 " feet}}$
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There are 100 cm in 1 mitre so 38 cm $= \frac{38}{100}$ of 1 metre

Thus, as feet, $38 c m = \frac{38}{100} \times 3.28125 \text{ feet}$

$38 c m \equiv 1.246875 \text{ feet" larr" exact value}$
