Subtract fractions with step-by-step solutions. Handles negative results and shows LCD process.
Problem: 1/4 - 3/4
Step 1: Denominators are the same (4)
Step 2: Subtract: 1 - 3 = -2
Step 3: Result: -2/4
Step 4: Simplify: -2/4 = -1/2
Answer: -1/2 or -0.5
Yes! When you subtract a larger fraction from a smaller one, you get a negative result. For example, 1/4 - 3/4 = -2/4 = -1/2. This is mathematically correct and represents a value less than zero.
First find the LCD (Least Common Denominator) of both fractions. Convert each fraction to an equivalent fraction with the LCD. Then subtract the numerators while keeping the common denominator. Finally, simplify if possible.
If denominators are the same, simply subtract the numerators and keep the denominator unchanged. For example: 5/8 - 2/8 = 3/8. Then simplify if needed.
Use the same process - find LCD, convert, and subtract. The result will be negative. For example, 2/5 - 4/5 = -2/5. The negative sign indicates the result is below zero.
Yes, it's easier to convert mixed numbers to improper fractions first. Subtract using the standard method, then convert back to a mixed number if desired. This avoids borrowing complications.
The process is nearly identical - both require finding the LCD and converting fractions. The only difference is the operation: you subtract numerators instead of adding them. Also, subtraction can produce negative results while addition of positive fractions cannot.
