How many millions make $$3$$ crores?
$$\textbf{Step 1: Conversion from crores to millions}$$
$$1$$ crore $$= 1,00,00,000$$
$$\therefore\ 3$$ crores $$= 3 \times 1,00,00,000$$
$$ = 30000000$$
$$ = 30 \times 1000000$$
$$= 30 \times 1$$ millions (since $$100000 = 1$$ million)
$$= 30$$ millions
$$\textbf{Hence, 30 millions make 3 crores}$$
