Question

Simplify the following.

$2.2\times{0.2}\div(0.4\times{\frac{1}{2}})-\frac{1}{2}\times{4}(1.04-0.2\times{0.2})$

• A. 0.5
• B. 0.2
• C. 0.3
• D. 0.6

Answer 1

Answer:

B. 0.2

Follow BODMAS rule to solve this question, as per the order given below, 

Calculation:

$2.2\times{0.2}\div({0.4}\times\frac{1}{2})-\frac{1}{2}\times4(1.04-0.2\times{0.2})$

$=2.2\times{0.2}\div(\frac{4}{10}\times{\frac{1}{2}})-\frac{1}{2}\times4(1.04-0.04)$

$=2.2\times0.2\div(\frac{4}{10}\times{\frac{1}{2}})-\frac{1}{2}\times{4}\times{1}$

$=2.2\times{0.2}\div(\frac{1}{5})-2$

$=2.2\times{0.2}\times{5}-2$

$=2.2\times{1}-2$

$=0.2$

∴$2.2\times{0.2}\div({0.4}\times\frac{1}{2})-\frac{1}{2}\times4(1.04-0.2\times{0.2})=0.2$
