Understanding Fractions

To add or subtract fractions, the denominators must be the same. Here are the steps to add or subtract fractions:

1. Find a Common Denominator: To add or subtract fractions, the denominators must be the same. If the denominators are not the same, find the least common denominator (LCD) by finding the least common multiple (LCM) of the denominators.

2. Perform the Operation: Once the fractions have the same denominator, add or subtract the numerators and keep the denominator the same.

Let's apply these steps to the given fractions.

Adding and Subtracting Fractions

1. Adding 1/5 + 1/5: - The denominators are the same, so we can add the numerators directly. - 1/5 + 1/5 = 2/5 2. Subtracting 7 3/8 - 5 5/8: - First, we need to convert the mixed numbers to improper fractions. - 7 3/8 = (7 * 8 + 3)/8 = 59/8 - 5 5/8 = (5 * 8 + 5)/8 = 45/8 - Now, we can subtract the fractions. - 7 3/8 - 5 5/8 = 59/8 - 45/8 = 14/8 = 7/4 = 1 3/4 3. Adding 2 2/3 + (-1 5/6): - First, we need to convert the mixed numbers to improper fractions. - 2 2/3 = (2 * 3 + 2)/3 = 8/3 - (-1 5/6) = -(1 * 6 + 5)/6 = -11/6 - Now, we can add the fractions. - 2 2/3 + (-1 5/6) = 8/3 - 11/6 = 5/6 4. Subtracting -5 1/3 + 4.5: - First, we need to convert the mixed number to an improper fraction. - -5 1/3 = -(5 * 3 + 1)/3 = -16/3 - Now, we can add the fractions. - -5 1/3 + 4.5 = -16/3 + 9/2 = -5/6 These are the results of adding and subtracting the given fractions and mixed numbers.
