# Simplify and round to the appropriate number of significant digits$(a)$ $16.235 \times 0.217 \times 5$ $(b)$ $0.00435 \times 4.6$

##### SOLUTION
Ans a-
$16.235 \times 0.217 \times 5 = 17.614975$
Since the least no.of significant digit is one, so the final answer should be rounded off upto one significant digit.
Therefore, Ans is $20$

Ans b-
$0.00435 \times 4.6 = 0.02001$
Since the least no.of significant digit is two, so the final answer should be rounded off upto two significant digit.
Therefore, Ans is $0.02$
