Question

$3\times 1000+2\times 10+\frac{4}{10}+\frac{3}{1000}$ is the expanded form of the number ____.

• A. $3200.430$
• B. $3002.403$
• C. $32.430$
• D. $3020.403$

Answer 1

The correct option is D $\left(3020.403\right)$

Given $3\times 1000+2\times 10+\frac{4}{10}+\frac{3}{1000}$
According to the BODMAS Rule, the first preference of operation is to simplify is $÷$.
So, $\frac{4}{10}=0.4$ and $\frac{3}{1000}=0.003$
Thus, the given expression can be written as
$=3\times 000+2\times 0+0.4+0.003$
The next operation is to simply is multiplication,
So, $=3000+20+0.4+0.003$
$=3020.403$
Therefore, the value of the given expression is $=3020.403$
