Question

Ms. Malle owns a restaurant. Typically 3/20 of the customer’s order fish, while 7/20 of the customer’s order poultry. What fraction of her customers order either fish or poultry?

Answer 1

3/20 order fish and 7/20 customers order poultry. You combine both of those fractions together to receive 10/20 which simplified is 1/2. Half of her customers order either fish or poultry and the other half order something else.
