Write the sum.
$\frac{1}{2} + \frac{1}{4} + \frac{1}{8}$
Convert to common denominator 8.
$\frac{1}{2} = \frac{4}{8}$ $\frac{1}{4} = \frac{2}{8}$ $\frac{1}{8} = \frac{1}{8}$
Add the fractions.
$\frac{4}{8} + \frac{2}{8} + \frac{1}{8} = \frac{7}{8}$
Final answer: $\frac{7}{8}$
\dfrac{7}{8}

Calculate $\left( \frac{2}{3} \right)^2$ .
$\left( \frac{2}{3} \right)^2 = \frac{4}{9}$
Subtract $\frac{2}{9}$ .
$\frac{4}{9} - \frac{2}{9}$
Simplify.
$\frac{4 - 2}{9} = \frac{2}{9}$
Final answer: $\frac{2}{9}$
\dfrac{2}{9}

Find the discount amount.
Original price: R50
Paid: R49
Discount: R50 - R49 = R1
Percentage discount formula.
$\frac{\text{discount}}{\text{original price}} \times 100\%$
Substitute values.
$\frac{\text{R1}}{\text{R50}} \times 100\%$
Simplify.
$\frac{1}{50} \times 100\% = 2\%$
Final answer: 2%
