Grace is taking \( 7 / 8 \) of a tablespoon of cold medicine 3 times a day. How much cold medicine is she taking in one day?

In one day, Grace takes \( \frac{7}{8} \) tablespoon three times. To find her total daily intake, you would multiply the dosage by the number of doses: \[ 3 \times \frac{7}{8} = \frac{21}{8} \text{ tablespoons}. \] This means Grace is taking \( 2 \frac{5}{8} \) tablespoons of cold medicine in total each day. To make sure you are calculating properly, it’s important to convert improper fractions to mixed numbers accurately and to ensure you’re benefiting from a common denominator when adding fractions together. This helps avoid errors, especially when the fractions get larger. Always double-check your calculations!
