If 2994 ÷14.5 = 172, then 29.94 ÷1.45 = ?

A. 1.72
B. 0.172
C. 17.2
D) None of these

29.94/ 1.45 = ?

= 299.4/ 14.5

= 2994/ 14.5 \times 1/ 10

$= \frac{2994}{14.5} \times \frac{1}{10}$

Substitute 172 in the place of $= \frac{2994}{14.5} \times \frac{1}{10}$

$\begin{aligned} = \frac{172}{10} \\ = 17.2 \end{aligned}$

$\begin{aligned} = \frac{172}{10} \\ = 17.2 \end{aligned}$
