1

Evaluate the following:

$7\frac{1}{3}\div6\frac{2}{3}$

$1\frac{1}{3}$

$6\frac{1}{10}$

$1\frac{6}{10}$

$\frac{65}{60}$

$1\frac{1}{10}$

Explanation

Start by converting 71/3 to 22/3, and 6 2/3 to 20/3. We then multiply 22/3 by the reciprocal of 20/3, 3/20, and you get 66/60. This simplifies to 11/10.

2

Simplify the following expression:

$\frac{2}{3}\div\frac{5}{6}$

$\frac{5}{9}$

$\frac{7}{9}$

$\frac{4}{5}$

$\frac{1}{5}$

Explanation

$\frac{2}{3}\div\frac{5}{6}=\frac{2}{3}\times\frac{6}{5}=\frac{12}{15}=\frac{4}{5}$

3

$\dpi{100} \small \frac{1}{3}\div \frac{3}{5} =$

$\dpi{100} \small \frac{5}{9}$

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

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

$\dpi{100} \small \frac{3}{8}$

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

Explanation

Cross multiply or multiply using the reciprocal of the second fraction.

4

Solve.

$\small \frac{2}{5}\div \frac{1}{25}=$

$\small \frac{2}{5}$

$\small \frac{1}{15}$

$\small \frac{27}{5}$

$\small \frac{1}{2}$

Explanation

Remember, to divide a number by a fraction, multiply the number by the reciprocal of the fraction. In this case, $\small \small \frac{2}{5}\div \frac{1}{25}=\frac{2}{5}\times \frac{25}{1}=\frac{50}{5}=10$
