Q:

6 divided by 2(1 + 2) =

A) 1 B) 0
C) 9 D) Can't be determined
 
Answer & Explanation Answer: C) 9

Explanation:

The given expression can be simplified as

÷ 2 (1 + 2)

The expression can be simplified further by the order of operations, using BODMAS rule.

 

First evaluate Parentheses/Brackets, then evaluate Exponents/Orders, then evaluate Multiplication-Division, and finally evaluate Addition-Subtraction.

 

Now, the expression becomes ÷ 2 (3)

 

According to the order of operations, division and multiplication have the same precedence, so the correct order is to evaluate from left to right. First take 6 and divide it by 2, and then multiply by 3.

6 ÷ 2 × 3

= 3 × 3

= 9

But not  6÷2×3 = 6 ÷ 6 = 1

Hence, 6 ÷ 2 (1 + 2) = 9.

Q:

Every rational number is an integer.

A) TRUE B) FALSE
Answer & Explanation Answer: B) FALSE

Explanation:

Any integer 'i' can be written as i = i/1, which is a rational number. Clearly, 7/2,-5/4, etc... are rational numbers but they are not integers.


Hence, from the above analysis, every integer is a rational number but a rational number need not be an integer.


 


Therefore the given statement that 'Every rational number is an integer' is FALSE.
