√3/√12 = √3/(√3*√4) = 1/√4 = 1/2 = 50%

Hence option E is correct

==> According to the ivy approach, you get is:”=”, what: “some”, and percent:”1/100”. Also, you substitute √12=2√3, and from √3=some(1/100)2√3, if you get rid of √3 on both sides, you get 1=(some)2/100, some=50.

The answer is E.
Answer: E

My approach:

√3/√12
√3/√4 x √3
1.3/2 x 1.3
1.3/2.6

Rationalizing denominator (getting rid of radical) is very quick. (< 30 seconds)

\(\frac{\sqrt{3}}{\sqrt{12}}\)

Multiply numerator and denominator by \(\sqrt{12}\)

\(\frac{\sqrt{3}}{\sqrt{12}}*\frac{\sqrt{12}}{\sqrt{12}}=\frac{\sqrt{36}}{12}\)

\(\frac{\sqrt{36}}{12}=\frac{6}{12}\)

\(\frac{6}{12}\) = 50%

Very easy I did this way
√3=x/100*√12
x=√3*100/√12
multiply and divide by √12
x=√36*100/12
x=6*100/12
x=50%

√3 is what percent of √12?

A. 20%
B. 25%
C. 30%
D. 46%
E. 50%

\(\sqrt{3}\) = x% of \(\sqrt{{12}}\)
\(\frac{x}{100}\) * \(\sqrt{{2^2*3}}\) = \(\sqrt{3}\)
x = \(\sqrt{3}\) x 100 / 2\(\sqrt{3}\) = 50%
Answer E...
