To subtract mixed numbers, follow these steps:
1. Find the least common denominator (LCD) of the fractions.
2. Convert the mixed numbers into improper fractions.
3. Subtract the fractions.
4. Simplify, if needed.
Step 1: The least common denominator (LCD) of 11 is itself. So we do not need to find a new denominator.
Step 2: Converting the mixed numbers to improper fractions:
v-4 5/11 = (11 * v - 4 + 5) / 11 = (11v - 4 + 5) / 11 = (11v + 1) / 11
2 4/11 = (11 * 2 + 4) / 11 = (22 + 4) / 11 = 26/11
Step 3: Subtract the fractions:
(11v + 1) / 11 - 26/11 = (11v + 1 - 26) / 11 = (11v - 25) / 11
Step 4: Simplify, if needed. Since we cannot simplify any further, the result is:
v-4 5/11 - 2 4/11 = (11v - 25) / 11
What isv-4 5/11 - 2 4/11
