Question

Every morning ,Halle goes to school with a liter bottle of water . She drinks 1/4 of the bottle before school starts and 2/3 of the rest before lunch . How many milliliters are left in the bottle at lunch

Answer 1

Halle drinks 250 milliliters of her 1,000-milliliter water bottle before school and 500 milliliters before lunch, leaving her with 250 milliliters at lunch.

Step-by-step explanation:

The question is about calculating the amount of water left in a bottle after Halle drinks portions of it at two different times. Halle starts with a 1-liter bottle of water, which is equivalent to 1,000 milliliters since there are 1,000 milliliters in a liter. Before school starts, she drinks 1/4 of the bottle, which is 250 milliliters (1/4 of 1,000 milliliters). This leaves her with 750 milliliters of water. Then, she drinks 2/3 of the remaining water before lunch, which is 2/3 of 750 milliliters. This equals 500 milliliters. Therefore, 250 milliliters of water are left in the bottle at lunch.

To solve this step by step:

1. Calculate 1/4 of the 1,000 milliliters: 1,000 mL × 1/4 = 250 mL.
2. Subtract this amount from the initial volume: 1,000 mL - 250 mL = 750 mL remaining.
3. Next, calculate 2/3 of the remaining 750 milliliters: 750 mL × 2/3 = 500 mL consumed before lunch.
4. Finally, subtract the consumed amount from the remaining amount: 750 mL - 500 mL = 250 mL left at lunch.

Answer 2

the question should say how much water is left in percent or fraction.
