To solve , we need to perform the following steps:
Therefore, the result of the subtraction is .
\( \frac{1}{3}+\frac{1}{4}= \)
Because fractions represent parts of different wholes! means 6 parts out of 10, while means 1 part out of 3. You need the same denominator to compare them.
List the multiples of each number: 10: 10, 20, 30, 40... and 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30... The first number that appears in both lists is 30, so LCD = 30.
Yes! Always check if your answer can be simplified. Divide both numerator and denominator by their greatest common factor. becomes when divided by 2.
Great! That makes it easier. If you had , since 10 ÷ 5 = 2, you'd just convert to and subtract directly.
