Final answer:
Katie used 6 grams of tea leaves to make tea last week.
Step-by-step explanation:
To find out how many grams of tea leaves Katie used to make tea last week, we can set up a proportion using the ratio of the tea leaves to the fluid ounces:
6 grams / 24 fluid ounces = x grams / y fluid ounces
Since we know that Katie used 24 fluid ounces of tea, we can plug that value into the equation:
6 grams / 24 fluid ounces = x grams / 24 fluid ounces
Cross-multiplying gives us:
24x = 6 * 24
Simplifying, we get:
24x = 144
Dividing both sides by 24, we find that x = 6 grams.
Therefore, Katie used 6 grams of tea leaves to make tea last week.
