Solve the following exercise:
65−31−122=?
To solve the subtraction of three fractions, follow these steps:
- Step 1: Identify the denominators of the fractions: 6, 3, and 12.
- Step 2: Determine the least common denominator (LCD), which is the least common multiple of 6, 3, and 12. The LCD is 12.
- Step 3: Convert each fraction to an equivalent fraction with the LCD of 12.
- 65=6×25×2=1210
- 31=3×41×4=124
- 122 remains 122.
- Step 4: Perform the subtraction with these equivalent fractions:
1210−124−122.
- Step 5: Subtract the fractions:
1210−4−2=124.
- Step 6: Simplify the resulting fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 4:
124=12÷44÷4=31.
Therefore, the solution to the problem is 31.
