4. \( 3 / 4-1 / 3= \)

To solve \( 3/4 - 1/3 \), first, we need a common denominator. The least common denominator of 4 and 3 is 12. Converting the fractions gives us \( 9/12 - 4/12 \). Now, you can easily subtract: \( 9/12 - 4/12 = 5/12 \). So, the answer is \( 5/12 \). Now, don't forget, when dealing with fractions, keeping track of your denominators can save you a lot of time and avoid pesky mistakes! Simplifying fractions whenever possible can also make your life easier. Consider \( 10/20 \), which simplifies directly to \( 1/2 \)—a much easier computation for your next math adventure!
