What is a fraction?

A fraction is a numerical quantity that represents a part of a whole, typically expressed as one number (the numerator) divided by another number (the denominator) and written in the form a/b, where a is the numerator and b is the denominator. Fractions are used to represent values that are not whole numbers or integers and are essential in representing portions, ratios, and percentages in mathematics.

How do you add fractions with the same denominator?

To add fractions with the same denominator, you simply add the numerators together while keeping the denominator the same. For example, if you are adding 1/4 and 2/4, you would add the numerators together (1 + 2 = 3) and keep the denominator the same (4). So, the result would be 3/4.

How do you add fractions with different denominators?

To add fractions with different denominators, you first need to find a common denominator by identifying the least common multiple (LCM) of the denominators. Once you have a common denominator, you convert both fractions to have the same denominator by multiplying each fraction by a form of 1 that will not change its value (the equivalent of multiplying by 1). Then, you can simply add the numerators together and keep the common denominator to get the sum of the fractions.

How do you simplify a fraction?

To simplify a fraction, you need to find the greatest common factor (GCF) of the numerator and denominator and then divide both the numerator and denominator by that factor. This process reduces the fraction to its simplest form where the numerator and denominator have no common factors other than 1. Keep repeating this process until the fraction cannot be simplified further.

How do you subtract fractions with the same denominator?

To subtract fractions with the same denominator, simply subtract the numerators and keep the same denominator. For example, if you have 3/6 - 1/6, you would subtract 1 from 3 to get 2, and the denominator remains 6, so the answer is 2/6. If needed, simplify the resulting fraction by finding the greatest common factor between the numerator and denominator.

How do you subtract fractions with different denominators?

To subtract fractions with different denominators, you first need to find a common denominator by finding the least common multiple (LCM) of the denominators. Once you have a common denominator, you can rewrite each fraction with that common denominator and then subtract the numerators. Finally, simplify the resulting fraction if needed by reducing it to its simplest form.

What is a mixed number?

A mixed number is a combination of a whole number and a fraction, written together. It represents a quantity that is greater than one, but also includes a part that is less than one.

How do you convert a mixed number to an improper fraction?

To convert a mixed number to an improper fraction, you multiply the whole number by the denominator of the fraction, then add the numerator. The result becomes the new numerator, while the denominator remains the same. So for a mixed number like 3 1/2, it would convert to an improper fraction as 3 * 2 + 1 = 7, making it 7/2.

How do you convert an improper fraction to a mixed number?

To convert an improper fraction to a mixed number, divide the numerator by the denominator. The whole number part of the quotient becomes the whole number of the mixed number. The remainder becomes the new numerator, with the original denominator remaining the same. This creates the mixed number format with the whole number and the proper fraction together.

How do you find a common denominator for adding or subtracting fractions?

To find a common denominator for adding or subtracting fractions, you need to identify the least common multiple (LCM) of the denominators of the fractions you are working with. Once you have determined the LCM, you can then rewrite each fraction using the common denominator and perform the addition or subtraction operation as needed. Remember to simplify the resulting fraction, if possible, by reducing it to its simplest form.
