Apr 17, 2024 · 1 * 2 = 2, and 2 + 1 = 3. Place the answer 3 over the original denominator and you have 3/2. To convert 2 3/4 to a mixed number, multiply the whole number 2 by the denominator 4. 2 * 4 = 8. Next, add this number to the original numerator and place it over the original denominator. 8 + 3 = 11. Put 11 over 4 to get 11/4.
Adding and Subtracting Mixed Fractions. A Mixed Fraction is a. whole number and a fraction combined: 1 3 4. (one and three-quarters) To make it easy to add and subtract them, just convert to Improper Fractions first: An Improper fraction has a. top number larger than or equal to.
Step 1: Convert both the mixed fractions to improper fractions. Therefore, 22 3 2 2 3 will become 8/3; and 1 1 3 1 1 3 will become 4/3. Step 2: Add the fractions by adding the numerators because the denominators are the same. This will be 8/3 + 4/3 = 12/3. Step 3: Reduce the fraction, if required.
We can use the two methods to add the mixed numbers. Step I: We add the whole numbers, separately. Step II: To add fractions, we take L.C.M. of the denominators and change the fractions into like fractions. Step III: We find the sum of the whole numbers and the fractions in the simplest form.
Rewrite each fraction with a denominator of 21. 9 21 + 2 21 = 11 21. Add the fractions by adding the numerators and keeping the denominator the same. Make sure the fraction cannot be simplified. 3 7 + 2 21 = 11 21. You can also add more than two fractions as long as you first find a common denominator for all of them.
