The Correct Answer and Explanation is:
Correct Answer: 786.89
To solve this problem, we need to find the total amount of dish soap Aleks has. The problem gives us two pieces of information: the amount of dish soap Aleks bought and the amount they already had at home. The keyword in the question is “total,” which indicates that we need to combine these two amounts. The mathematical operation for combining quantities is addition.
The two amounts are 562.75 milliliters and 224.14 milliliters. We need to add these two numbers together.
The calculation is: 562.75 + 224.14
To perform the addition correctly, especially with decimals, it is best to align the numbers vertically so that the decimal points line up. This ensures that you are adding digits with the same place value, such as hundredths to hundredths and tenths to tenths.
The setup looks like this:Generated code
562.75
+ 224.14
--------Now, we can add the numbers column by column, starting from the rightmost digit.
- Hundredths place: 5 + 4 = 9
- Tenths place: 7 + 1 = 8
- Decimal point: We bring the decimal point straight down into our answer.
- Ones place: 2 + 4 = 6
- Tens place: 6 + 2 = 8
- Hundreds place: 5 + 2 = 7
Putting all the digits together, the sum is 786.89.
Therefore, Aleks has a total of 786.89 milliliters of dish soap. The unit of measurement, milliliters, is important to include because it gives context to the numerical answer. By adding the newly purchased amount to the existing supply, we have successfully calculated the total volume of dish soap Aleks now possesses.
