Question

Which of the following tape diagrams represent an equivalent ratio of 1:2?

• A.
• B.
• C.
• D. None of these

Answer 1

The correct option is B

For option A
Ratio is 4:7 and it can not be simplified to 1:2

For option B
Ratio is 3:6
Also, on simplification
$\frac{3}{6}=\frac{3\times 1}{3\times 2}=\frac{1}{2}$
Hence 3:6 is equivalent ratio of 1:2

For option C
Ratio is 4:6
Also, on simplification
$\frac{4}{6}=\frac{2\times 2}{3\times 2}=\frac{2}{3}$

Therefore, option B is the correct answer.
