Question

Evaluate: $3.5\times 4-96.24÷2.4+3.6÷0.09$.

• A. $12.8$
• B. $11.9$
• C. $13.9$
• D. $14.8$

Answer 1

Answer: (C)

$13.9$

BODMAS is an acronym that shows us which operation to do first and how to order them. We have learnt the operations of addition, subtraction, multiplication and division. It is easy to carry out these operations separately. But sometimes we have to solve all these operations in one example. At that time to get proper answer there are some rules and we should follow the rules of BODMAS.

BODMAS is an acronym for-

#Brackets

#Orders

#Division

#Multiplication

#Addition

#Subtraction

Now, we use BODMAS rule to solve the given expression as follows:

$=3.5\times 4-96.24÷2.4+3.6÷0.09=(3.5\times 4)-(96.24÷2.4)+(3.6÷0.09)=14-40.1+40=(14+40)-40.1$

$=54-40.1=13.9$

Hence, $3.5\times 4-96.24÷2.4+3.6÷0.09=13.9$
