Understanding the Relationship Between Gallons and Cups of Water

When it comes to measuring the amount of water Katrina drinks in a week, we need to convert the given units from gallons to cups. This requires a clear understanding of the relationship between gallons and cups, as well as the concept of unit conversion.

The Importance of Unit Conversion in Mathematics

Unit conversion is a fundamental concept in mathematics that involves changing the units of measurement of a quantity from one system to another. In this case, we are converting gallons to cups. This process is essential in various fields, including science, engineering, and everyday life.

Converting Gallons to Cups

To convert gallons to cups, we need to know that there are 16 cups in a gallon. This means that if Katrina drinks 0.5 gallons of water per day, we can convert this amount to cups by multiplying the number of gallons by the number of cups in a gallon.

The Correct Expression for Converting Gallons to Cups

The correct expression for converting gallons to cups is:

$$\frac{0.5 \text{ gallons}}{1 \text{ day}} \times \frac{16 \text{ cups}}{1 \text{ gallon}}$$

This expression represents the number of cups of water Katrina drinks in a day. To find the number of cups she drinks in a week, we need to multiply this amount by the number of days in a week.

Finding the Number of Cups of Water Katrina Drinks in a Week

Since there are 7 days in a week, we can multiply the number of cups Katrina drinks in a day by 7 to find the total number of cups she drinks in a week.

$$\frac{0.5 \text{ gallons}}{1 \text{ day}} \times \frac{16 \text{ cups}}{1 \text{ gallon}} \times 7 \text{ days}$$

This expression represents the total number of cups of water Katrina drinks in a week.

Conclusion

In conclusion, the correct expression for finding the number of cups of water Katrina drinks in a week is:

$$\frac{0.5 \text{ gallons}}{1 \text{ day}} \times \frac{16 \text{ cups}}{1 \text{ gallon}} \times 7 \text{ days}$$

This expression involves converting gallons to cups and then multiplying the result by the number of days in a week. By understanding the relationship between gallons and cups, we can accurately calculate the amount of water Katrina drinks in a week.
