Solve the following exercise:
To solve , we will follow these steps:
Now, let's work through these steps:
Step 1: Identify the Least Common Denominator (LCD)
The denominators are 12, 3, and 6. The least common denominator is 12.
Step 2: Convert each fraction
- The fraction  already has a denominator of 12.
- Convert  to a denominator of 12: .
- Convert  to a denominator of 12: .
Step 3: Perform the subtraction
Now that the fractions have the same denominator, subtract the numerators:
.
Therefore, the solution to the problem is .
\( \frac{1}{3}+\frac{1}{4}= \)
Because fractions represent parts of a whole! means 1 out of 3 equal parts, while means 1 out of 6 equal parts. You need the same-sized pieces (same denominator) to subtract properly.
List the multiples of each number: 12 (12, 24, 36...), 3 (3, 6, 9, 12...), 6 (6, 12, 18...). The smallest number that appears in all lists is 12, so that's your LCD!
Always check if you can simplify! Look for common factors in the numerator and denominator. Since has no common factors besides 1, it's already in simplest form.
Yes, but be careful! You could solve first, then subtract . Just make sure to use the LCD at each step to avoid errors.
Decimal conversion can introduce rounding errors! For exact answers, always work with fractions. You can convert your final fraction answer to a decimal to check: .
