How to solve fractions
Fraction Operations
1. Simplifying Fractions
Trick: Always simplify the fraction to its lowest terms before performing any operations.
How: Find the greatest common divisor (GCD) of the numerator and denominator, then divide both by the GCD.
Example: 8/12
GCD of 8 and 12 is 4.
Simplify: 8 Ă· 4 / 12 Ă· 4 = 2/3
2. Adding Fractions with the Same Denominator
Trick: When fractions have the same denominator, just add the numerators.
How: Keep the denominator the same and add the numerators.
Example: 3/8 + 5/8
Add the numerators: 3 + 5 = 8.
The answer is: 8/8 = 1.
3. Adding Fractions with Different Denominators
Trick: Find the Least Common Denominator (LCD) to make the denominators the same.
How: Multiply each fraction by a form of 1 that changes its denominator to the LCD.
Example: 2/5 + 3/4
LCD of 5 and 4 is 20.
Multiply 2/5 by 4/4 to get 8/20.
Multiply 3/4 by 5/5 to get 15/20.
Add the numerators: 8 + 15 = 23.
The answer is: 23/20, or 1 3/20.
4. Subtracting Fractions with the Same Denominator
Trick: Just subtract the numerators when the fractions have the same denominator.
How: Keep the denominator the same and subtract the numerators.
Example: 7/10 – 3/10
Subtract the numerators: 7 – 3 = 4.
The answer is: 4/10, or 2/5 after simplification.
5. Subtracting Fractions with Different Denominators
Trick: Like addition, you must find the Least Common Denominator (LCD), but this time subtract instead of adding.
How: Follow the same steps as for addition, but subtract the numerators.
Example: 5/6 – 2/3
LCD of 6 and 3 is 6.
Multiply 2/3 by 2/2 to get 4/6.
Now subtract: 5 – 4 = 1.
The answer is: 1/6.
6. Multiplying Fractions
Trick: Multiply the numerators together and the denominators together.
How: There is no need to find common denominators. Just multiply the numerators and denominators separately.
Example: 2/3 Ă— 4/5
Multiply the numerators: 2 Ă— 4 = 8.
Multiply the denominators: 3 Ă— 5 = 15.
The answer is: 8/15.
7. Dividing Fractions
Trick: Flip the second fraction (take its reciprocal) and then multiply.
How: Divide by multiplying by the reciprocal of the second fraction.
Example: 2/3 Ă· 4/5
Flip the second fraction to get 5/4.
Now multiply: 2/3 Ă— 5/4 = 10/12.
Simplify: 10/12 = 5/6.
The answer is: 5/6.
8. Converting Mixed Numbers to Improper Fractions
Trick: Multiply the whole number by the denominator and add the numerator.
How: Use the formula whole number Ă— denominator + numerator
to convert to an improper fraction.
Example: Convert 2 3/4 to an improper fraction.
2 Ă— 4 + 3 = 8 + 3 = 11.
The improper fraction is: 11/4.
9. Converting Improper Fractions to Mixed Numbers
Trick: Divide the numerator by the denominator, the quotient is the whole number, and the remainder is the numerator.
How: Perform long division to find the whole number and the remaining fraction.
Example: Convert 7/3 to a mixed number.
Divide 7 by 3: 7 Ă· 3 = 2 remainder 1.
The mixed number is: 2 1/3.
