Solve the following exercise:
To solve this problem, we need to subtract three fractions: .
First, let's find the least common denominator (LCD) for the fractions. The denominators are 2, 6, and 12. The smallest number that all these denominators divide evenly into is 12, so the LCD is 12.
Next, convert each fraction to have 12 as the denominator:
Now, perform the subtraction using these equivalent fractions:
Subtract the fractions in sequence while keeping the common denominator:
Then,
The fraction is already in its simplest form.
Therefore, the solution to the problem is .
\( \frac{1}{3}+\frac{1}{4}= \)
Fractions represent parts of different-sized wholes! means 1 out of 2 pieces, while means 1 out of 6 pieces. You need the same-sized pieces (same denominator) to subtract them.
Look for the smallest number that all denominators divide into evenly. For 2, 6, and 12: since 12 ÷ 2 = 6, 12 ÷ 6 = 2, and 12 ÷ 12 = 1, the LCD is 12!
Always check if your answer can be reduced! Look for common factors in the numerator and denominator. Since has no common factors other than 1, it's already in lowest terms.
With subtraction, work left to right! First do , then . This keeps your work organized and prevents errors.
That's possible with subtraction! If the fractions you're subtracting are larger than the first fraction, you'll get a negative result. Just keep the negative sign with your final answer.
