Given:

• $\frac{7}{12} \div \frac{ - 7}{12}$

To find:

• Solve the expression.

Solution:

Concept to be used:

$\bf \frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}$

Step 1:

Write the mathematical expression as per concept.

$\frac{7}{12} \div \frac{ - 7}{12} = \frac{7}{12} \times \frac{12}{ - 7}$

Step 2:

Cancel the common factors of numerator and denominator.

$\frac{7}{12} \div \frac{ - 7}{12} = \frac{ \cancel 7}{ \cancel{12}} \times \frac{\cancel{12}}{ - \cancel{7}}$

or

$\frac{7}{12} \div \frac{ - 7}{12} = \frac{1}{ - 1}$

or

$\frac{7}{12} \div \frac{ - 7}{12} = - 1$

Thus,

The value of $\bf \frac{7}{12} \div \frac{ - 7}{12} = - 1$
