L \( 0 / 1 \) 23- Emily works at the coffee shop, The coffee cups can hold \( 7 / 9 \) of a pint of liguld, if Emily pours \( 2 / 3 \) of a pint of coffee how much milk can a customer add? a) The customer can put in \( 2 / 9 \) of a pint of milk in the cup. b) The customer can put in \( 3 / 9 \) of a pint of milk in the cup. (5) The customer can put in \( 1 / 9 \) of a pint of milk in the cup. (d) The customer can put in \( 5 / 9 \) of a pint of milk in the cup.

To figure out how much milk the customer can add, we first determine how much coffee and milk can fit in the cup. The coffee cup can hold \( \frac{7}{9} \) of a pint, and Emily pours \( \frac{2}{3} \) of a pint of coffee. First, convert \( \frac{2}{3} \) to a fraction with a denominator of 9. \( \frac{2}{3} = \frac{6}{9} \). Now, subtract the amount of coffee from the total capacity of the cup: \[ \frac{7}{9} - \frac{6}{9} = \frac{1}{9}. \] So, the customer can add \( \frac{1}{9} \) of a pint of milk, which corresponds to option (c). The answer is (c) The customer can put in \( \frac{1}{9} \) of a pint of milk in the cup. In a fun twist, it's like a little puzzle - Emily and the customer are teaming up to create the perfect cup of coffee! Who knew math could be so delicious? You might want to consider brewing this arithmetic magic into your daily routine as a delightful coffee ritual—perhaps even involve friends in evaluating what mix of coffee and milk they enjoy the most!
