ADDING AND SUBTRACTING: Need a common denominator
DIVIDING: Multiply the numerator fraction by the inverse of the denominator fraction
To subtract fractions, you need to have a common denominator. Here's how you can subtract fractions step by step:
1. Find a common denominator: Check if the fractions you want to subtract already have a common denominator. If they don't, find the least common multiple (LCM) of the denominators, and use it as the common denominator for both fractions.
2. Adjust the fractions: Once you have the common denominator, adjust the numerators of the fractions by multiplying each numerator by the same value you used to obtain the common denominator.
3. Subtract the numerators: Now that you have both fractions with the same denominator, subtract the numerators. Keep the denominator the same.
4. Simplify if necessary: If the resulting fraction is an improper fraction (the numerator is larger than the denominator), simplify it to a mixed number if needed or reduce it to its simplest form.
To divide fractions, you need to multiply the first fraction by the reciprocal (inverse) of the second fraction. Here are the steps for dividing fractions:
1. Take the reciprocal: To divide a fraction by another fraction, swap the numerator and denominator of the second fraction. This means that if you have a fraction a/b, the reciprocal is b/a.
2. Multiply the fractions: Multiply the first fraction by the reciprocal of the second fraction. Multiply the numerators together and the denominators together.
3. Simplify if necessary: Reduce the resulting fraction to its simplest form if possible, using common factors of the numerator and the denominator.
Remember to always check your answers and simplify fractions when necessary to get them into their simplest form.
