multiple - choice question
how can you make 3 into a fraction?
by writing it as (\frac{3}{x})
by writing it as (\frac{3}{1})
by writing it as (\frac{3}{0})

Explanation:

To convert an integer to a fraction, we can write it with a denominator of 1 because any number divided by 1 is the number itself. So 3 can be written as $\frac{3}{1}$. Writing it as $\frac{3}{x}$ is incorrect as $x$ is a variable and not related to representing 3 as a fraction, and $\frac{3}{0}$ is undefined (division by zero is not allowed).

Answer:

B. By writing it as $\frac{3}{1}$ (assuming the middle option is labeled B, if the options are labeled with A, B, C where A is "By writing it as $\frac{3}{x}$", B is "By writing it as $\frac{3}{1}$", C is "By writing it as $\frac{3}{0}$")
