A. 25%
B. 30%
C. 35%
D. 40%
Answer & Solution
Answer: The correct answer is 25%.
Solution:
By using Substitution we form an equation
What\ \ \ \ \ Percent\ \ \ \ \ is\ \ \ \ \ \ \frac{3}{12}
\downarrow\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \downarrow\ \ \ \ \ \ \ \ \ \ \ \ \downarrow\ \ \ \ \ \ \ \ \ \downarrow\
x\ \ \ \ \ \ \ \ \ \ \ \ \ \ \frac{1}{100}\ \ \ \ \ \ \ \ \ \ =\ \ \ \ \ \ \frac{3}{12}
x\ \times\frac{1}{100}=\frac{3}{12}
x\ =\frac{3}{12}\times100
x\ =\frac{1}{4}\times100\ \ OR\ \ \frac{300}{12}
x\ =\ 25\%
Hence, 25 percentage is 3/12.
Alternate Method:
Also if the question is given like this: Convert 3/12 into percentage
you can solve it in simple way. Just multiply it with 100 to convert any number in percentage.
x\ =\frac{3}{12}\times100
x\ =\frac{1}{4}\times100\ \ OR\ \ \frac{300}{12}
x\ =\ 25\%
