Example Question #81 : Fractions

Possible Answers:

Correct answer:

Explanation:

When dividing fractions, first find the reciprocal of the second fraction and change the problem to multiplication:

You then treat the problem like any other multiplication problem and multiply straight across.

Since the numerator is larger than the denominator, we know our answer will be greater than 1.

6 divides into 8 one time, with 2 remaining. The 2 remains on top of the 6 as the numerator. This answer can still be reduced; however, as 2 and 6 are both evenly divisible by 2.

 

Your final answer is 

Example Question #1 : How To Multiply

\dpi{100} \frac{\frac{1}{2}\times \frac{1}{3}}{\frac{1}{9}}=

Possible Answers:

\dpi{100} \frac{2}{3}

\dpi{100} \frac{1}{9}

\dpi{100} \frac{3}{2}

\dpi{100} \frac{1}{54}

Correct answer:

\dpi{100} \frac{3}{2}

Explanation:

First multiply the fraction in the numerator.

\dpi{100} \frac{1}{2}\times \frac{1}{3}=\frac{1\times 1}{2\times 3}=\frac{1}{6}

Now we have \dpi{100} \frac{\frac{1}{6}}{\frac{1}{9}}

Never divide fractions.  We multiply the numerator by the reciprocal of the denominator.

\dpi{100} \frac{\frac{1}{6}}{\frac{1}{9}}=\frac{1}{6}\div \frac{1}{9}=\frac{1}{6}\times \frac{9}{1}=\frac{1\times 9}{6\times 1}=\frac{9}{6}=\frac{3}{2}

Example Question #2 : How To Multiply

Which of these expressions is the greatest?

Possible Answers:

One fifth of

Twenty percent of one fourth

Twenty-five percent of one fifth

All of these expressions are equivalent

One fourth of

Correct answer:

All of these expressions are equivalent

Explanation:

The easiest way to see that all four are equivalent is to convert each to a decimal product, noting that twenty percent and one-fifth are equal to , and twenty-five percent and one fourth are equal to .

One fourth of 0.2: 

One fifth of 0.25: 

Twenty-five percent of one fifth:

Twenty percent of one fourth:
