Explanation
The correct answer is 2.2 because when you multiply 2.5 by 0.88, you get 2.2.

Explanation
To find the result of dividing 5.25 by 0.05, we can convert the decimal divisor 0.05 into a whole number by moving the decimal point two places to the right, resulting in 5. Dividing 5.25 by 5 gives us 1.05, which can be expressed as 105 when the decimal point is moved two places to the right. Therefore, the correct answer is 105.

Explanation
To convert a mixed number into a decimal, we first convert the fraction part into a decimal. In this case, the fraction 3/5 can be converted to 0.6 by dividing 3 by 5. Then, we add the whole number part (5) to the decimal part (0.6) to get the final decimal value, which is 5.6.

Explanation
When adding or subtracting decimals, it is necessary to line up the decimal points. This is because the decimal point represents the separation between the whole number and the fractional part of the decimal. By aligning the decimal points, it ensures that the corresponding place values are being added or subtracted correctly. If the decimal points are not lined up, the calculation would be inaccurate and the result would not be correct. Therefore, it is important to line up the decimal points when performing addition or subtraction with decimals.

Explanation
The given expression is a multiplication of three numbers: 1.3, 2.4, and 6.8. When these numbers are multiplied together, the result is 21.216.

Explanation
When rounding a number to the nearest tenths place, we look at the digit in the hundredths place. If it is 5 or greater, we round up. In this case, the digit in the hundredths place is 6, which is greater than 5. Therefore, we round up the tenths place to 7, resulting in the number 34.7.
