Question

If a/b = 2, what is the value of 4b/a?
A) 0
B) 1
C) 2
D) 4

Answer 1

Answer:

C

Step-by-step explanation:

given $\frac{a}{b}$ = 2 ( multiply both sides by b )

a = 2b

⇒ $\frac{4b}{a}$ = $\frac{4b}{2b}$ = 2 →  C

Answer 2

Answer:

Option C) 2

Step-by-step explanation:

We are given the following information in the question:

$\displaystyle\frac{a}{b} = 2$

We have to find the value of $\displaystyle\frac{4b}{a}$.

The solving can be done in the following manner:

$\displaystyle\frac{a}{b} = 2\\\\\RIghtarrow \frac{b}{a} = \frac{1}{2}\\\\\text{Multiplyimg both sides by 4}\\\\4\times \frac{b}{a} =4\times \frac{1}{2}\\\\\frac{4 b}{a} = \frac{4}{2} = 2$

Option C) 2 is the correct answer.
