Solved by back substitution

2 of the answer choices have a "1" for the second part of the ratio. Only way this is possible is if both parts are multiplied by 3.

Thus 6 : 1

(E) 1 to 6


When setting up ratios, we can set up a ratio in fraction form. For example, if we were told the ratio of a to b is 1 to 2, we could say: a/b = ½.

Since we are given the ratio of 2 to 1/3, we can write this as:

2/(1/3)

We simplify this complex fraction by multiplying both the numerator and denominator by 3, obtaining:

(2 x 3)/1 = 6/1

Thus, the equivalent ratio is 6 to 1.

Answer: A

\(2\) : \(\frac{1}{3}\)

Multiply both sides by 3

\(2*3\) : \(\frac{1}{3}*3\)

=> 6 : 1

Hence answer will be (A)
