Final answer:
7 paper cups can be filled from a 1.75 liter bottle of water.
Step-by-step explanation:
The student is asking how many 250 ml paper cups can be filled from a 1.75 liter bottle of water. To find the answer, we must convert liters to milliliters because the volume of the paper cups is given in milliliters (ml).
Since 1 liter is equal to 1000 milliliters, the bottle's volume in milliliters is 1.75 liters multiplied by 1000, which equals 1750 milliliters.
To determine the number of 250 ml paper cups that can be filled, we divide the total volume of the bottle in milliliters by the volume of one cup.
1750 ml ÷ 250 ml = 7 cups
Thus, the student can fill seven 250 ml paper cups from a 1.75 liter bottle of water.
It's important to use consistent units when solving problems involving volume, and knowing the basic conversion factors such as 1 liter being the equivalent of 1000 milliliters.
