$\frac{\frac{2}{3} - \frac{1}{9}}{\frac{3}{4} + \frac{5}{6}}$

Short Answer

Expert verified

The simplified form of the given expression is $\frac{20}{57}$ .

Step by step solution

Step 1. Given information.

The given expression is:

$\frac{\frac{2}{3} - \frac{1}{9}}{\frac{3}{4} + \frac{5}{6}}$

Step 2. Concept.

The following concept is required for simplification:

$\frac{A}{B} \div \frac{C}{D} = \frac{A}{B} \cdot \frac{D}{C}$

Step 3. Rewrite the expression and then simplify.

Simplify the numerator and denominator.

$= \frac{\frac{6 - 1}{9}}{\frac{9 + 10}{12}} = \frac{\frac{5}{9}}{\frac{19}{12}}$

Rewrite as the product of first times the reciprocal of the second.

$= \frac{5}{9} \cdot \frac{12}{19} = \frac{5 \cdot 12}{9 \cdot 19} = \frac{20}{57}$

Step 4. Conclusion.

The simplified form of the given expression is $\frac{20}{57}$ .
