A mixed number is a whole number combined with a fraction. To convert a mixed number to a decimal, first, separate the whole number from the fraction.
For example, in the mixed number \(3 \frac{1}{4}\), the whole number is 3 and the fraction is \(\frac{1}{4}\).
Next, convert the fraction to a decimal by dividing the numerator by the denominator. In this case, divide 1 by 4 to get 0.25.
Finally, add the decimal to the whole number: \(3 + 0.25 = 3.25\).
Understanding this conversion is crucial when performing operations like addition or subtraction with mixed numbers. By converting to decimals, calculations become easier to handle.

Subtracting decimals involves a few simple steps. Align the decimal points of the numbers you are subtracting. This ensures all digits are in the correct place values (tenths, hundredths, etc.).
For example, in the subtraction \(3.25 - 6.5\), align the numbers as follows: \(3.25\)
\(- 6.50\)
Notice that we added a zero to 6.5 to match the decimal places.
Begin subtracting from the rightmost digit. If necessary, borrow from the next left digit. Since 5 cannot be subtracted from 0 in the hundredths place, borrow 1 from the tenths place: \(3.25 - 6.50 = -3.25\).
Understanding decimal subtraction is key in many areas of math, especially in dealing with measurements and precise calculations.

When the number being subtracted is larger than the number it is being subtracted from, the result will be negative.
Think of it as owing more money than you have. If you start with \(3.25 and spend \)6.50, you end up in debt by $3.25.
In mathematical terms, \(3.25 - 6.5\) results in a negative value because 6.5 is greater than 3.25.
To calculate the negative result, follow the same steps as regular subtraction but remember to attach a negative sign to the final answer. \[3.25 - 6.5 = -3.25\].
Having a good grasp of handling negative numbers can help avoid mistakes in various mathematical problems, including algebra and real-life financial situations.
