How do you perform addition of fractions with the same denominator?

To add fractions with the same denominator, simply add the numerators together while keeping the denominator the same. For example, to add 1/4 + 2/4, add the numerators (1+2 = 3) and keep the denominator as 4, resulting in 3/4. This is because when the fractions have the same denominator, it means they represent the same-sized pieces, making it easier to add them together.

How do you find a common denominator before adding fractions with different denominators?

To find a common denominator before adding fractions with different denominators, you need to identify the least common multiple (LCM) of the denominators of the fractions. This involves listing the multiples of each denominator and finding the smallest number that appears in both lists. Once you have the LCM, you can rewrite each fraction using the common denominator before adding them together. This ensures that the fractions have the same denominator, making it possible to add them accurately.

How do you subtract fractions with the same denominator?

To subtract fractions with the same denominator, you simply subtract the numerators and keep the denominator the same. For example, if you have 3/5 - 1/5, you subtract the numerators (3-1 = 2) and keep the denominator the same (5), which gives you the answer 2/5.

How do you subtract fractions with different denominators?

To subtract fractions with different denominators, you first need to find a common denominator. To do this, determine the least common multiple (LCM) of the two denominators. Then, rewrite each fraction with the common denominator and perform the subtraction. Subtract the numerators while keeping the common denominator the same. Simplify the resulting fraction if needed by reducing it to its simplest form.

What is the process for adding mixed numbers with the same denominator?

To add mixed numbers with the same denominator, you simply add the whole numbers together and then add the fractions together. Ensure the fractions have the same denominator and then add the numerators. Simplify the resulting fraction if needed by reducing it to its lowest terms.

How do you subtract mixed numbers with the same denominator?

To subtract mixed numbers with the same denominator, first subtract the whole numbers. Then subtract the fractions. Make sure to borrow from the whole number if the fraction in the first number is smaller than the fraction in the second number. Finally, simplify the result if possible by regrouping if needed.

How do you add fractions with mixed numbers and different denominators?

To add fractions with mixed numbers and different denominators, first convert the mixed numbers to improper fractions. Then find a common denominator for the fractions by finding the least common multiple of the two denominators. Once you have a common denominator, add the fractions together by adding the numerators and keeping the common denominator. Simplify the resulting fraction if needed.

How do you subtract fractions with mixed numbers and different denominators?

To subtract fractions with mixed numbers and different denominators, first convert the mixed numbers into improper fractions. Then find a common denominator between the two fractions and subtract the numerators. Simplify the resulting fraction if needed by finding the greatest common factor between the numerator and denominator. Remember to convert the improper fraction back into a mixed number if necessary for the final answer.

What is the process for adding fractions with whole numbers and the same denominator?

To add fractions with whole numbers and the same denominator, you first add the whole numbers together, then simply add the numerators of the fractions while keeping the denominator the same. For example, to add 2 1/3 and 3 2/3, you would add 2 + 3 for the whole numbers, which equals 5, then add the numerators of the fractions 1 + 2 for a total of 3, keeping the denominator of 3 the same. So the result would be 5 3/3, which can be simplified to 6.

How do you subtract fractions with whole numbers and the same denominator?

To subtract fractions with whole numbers and the same denominator, you keep the denominator the same and subtract the whole numbers separately. For example, to subtract 2 1/3 from 5 1/3, you first subtract the whole numbers (5 - 2 = 3), then subtract the fractions (1/3 - 1/3 = 0), resulting in a final answer of 3 with the same denominator.
