Example Question #1 : How To Find Out A Mixed Fraction From An Improper Fraction

Convert \dpi{100} \small \frac{21}{4} to a mixed number.

Possible Answers:

\dpi{100} \small 5\frac{1}{4}

\dpi{100} \small 20\frac{1}{4}

\dpi{100} \small 4\frac{1}{4}

\dpi{100} \small 5\frac{1}{2}

\dpi{100} \small \frac{4}{5}

Correct answer:

\dpi{100} \small 5\frac{1}{4}

Explanation:

4 goes into 21 five times. 5 becomes your whole number. There is a remainder of 1 and your denominator remains the same, so your fraction is \dpi{100} \small \frac{1}{4}.

\dpi{100} \small 5\frac{1}{4}

Example Question #2 : How To Find Out A Mixed Fraction From An Improper Fraction

What is \frac{23}{4}\displaystyle \frac{23}{4} written as a mixed number?

Possible Answers:

5\frac{1}{2}\displaystyle 5\frac{1}{2}

4\frac{1}{4}\displaystyle 4\frac{1}{4}

5\frac{3}{4}\displaystyle 5\frac{3}{4}

2\frac{1}{4}\displaystyle 2\frac{1}{4}

Correct answer:

5\frac{3}{4}\displaystyle 5\frac{3}{4}

Explanation:

\displaystyle 4 goes into \displaystyle 23 five times with a remainder of \displaystyle 3

The denominator does not change. 

Example Question #2 : How To Find Out A Mixed Fraction From An Improper Fraction

Which of the following is the mixed fraction equivalent to \displaystyle \frac{19}{3}?

Possible Answers:

\displaystyle \frac{13}{3}

\displaystyle 8\frac{2}{3}

\displaystyle 6\frac{3}{5}

\displaystyle 6\frac{1}{3}

\displaystyle \frac{3}{19}

Correct answer:

\displaystyle 6\frac{1}{3}

Explanation:

To begin, notice that using your calculator, you can find:

\displaystyle \frac{19}{3} = 6.33333...

Now, the closest even multiple of \displaystyle 3 that is less than \displaystyle 19 is \displaystyle 18.  Therefore, you know that your number is:

\displaystyle \frac{19}{3}=\frac{18}{3}+\frac{1}{3}

This is the same as:

\displaystyle 6+\frac{1}{3}, or simply, \displaystyle 6\frac{1}{3}.  This is your mixed fraction.

Example Question #1 : Mixed / Improper Fractions

Which of the following is equivalent to \displaystyle \frac{82}{4}?

Possible Answers:

\displaystyle 20\frac{1}{2}

\displaystyle 15\frac{3}{4}

\displaystyle 20\frac{3}{8}

\displaystyle 15\frac{1}{2}

\displaystyle 20\frac{1}{4}

Correct answer:

\displaystyle 20\frac{1}{2}

Explanation:

Although there are many ways to convert improper fractions into mixed fractions, the easiest way is to use your calculator to your advantage.  Begin by dividing \displaystyle 82 by \displaystyle 4.  This gives you \displaystyle 20.5. Therefore, you can eliminate all the options that have do not have \displaystyle 20 for their first portion. Next, multiply \displaystyle 0.5 by the denominator (\displaystyle 4), and get \displaystyle 2.  This means that you have \displaystyle 20 and \displaystyle \frac{2}{4}, or \displaystyle \frac{1}{2}.  Thus, your answer is \displaystyle 20\frac{1}{2}.

Example Question #3 : How To Find Out A Mixed Fraction From An Improper Fraction

What does \displaystyle \small \small \small \small \frac{32}{14}+\frac{6}{7} equal, expressed as a mixed number?

Possible Answers:

Correct answer:

Explanation:

Simplify the two fractions, then find a common denominator, then solve.

Example Question #2 : How To Find Out A Mixed Fraction From An Improper Fraction

Convert the improper fraction\displaystyle \frac{27}{6} to a mixed number. Reduce all fractions if possible.

Possible Answers:

\displaystyle 5\frac{1}{6}

\displaystyle \frac{6}{27}

\displaystyle 4\frac{1}{2}

\displaystyle 1\frac{6}{21}

\displaystyle 4\frac{3}{6}

Correct answer:

\displaystyle 4\frac{1}{2}

Explanation:

To convert a mixed number into a fraction, first divide the denominator into the numerator and record the remainder:

.

the result is the mixed number, with the remainder being put as the numerator over the old denominator:
\displaystyle \frac{27}{6} = 4 \frac{3}{6} = 4 \frac{1}{2} when we reduce.
