Solution:
To solve this, you need to divide the amount of sales you were responsible for by the total sales of the company.Your sales: R200,000.00Total sales: R800,000.00Fraction of the total sales:$$ \frac{\text{Your sales}}{\text{Total sales}} = \frac{R200,000.00}{R800,000.00} = \frac{200,000}{800,000} $$To simplify the fraction, divide both the numerator (top number) and the denominator (bottom number) by 200,000:$$ \frac{200,000}{800,000} = \frac{200,000 \div 200,000}{800,000 \div 200,000} = \frac{1}{4} $$So, your share of the total sales was 1/4 or 25%.
