In the above question, 1/3 + 1/3, there is a common denominator which is “3”. Hence the fractions can be added thus, 1/3 + 1/3 = 2/3.

The first step when multiplying fractions is to multiply the two numerators. The second step is to multiply the two denominators. Finally, simplify the new fractions. The fractions can also be simplified before multiplying by factoring out common factors in the numerator and denominator.

Before you can add or subtract fractions with different denominators, you must first find equivalent fractions with the same denominator, like this: Find the smallest multiple (LCM) of both numbers.

To add fractions there are Three Simple Steps: Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put that answer over the denominator. Step 3: Simplify the fraction (if needed)

Step 1: Separate the whole number from the fractions. Step 2: Now we will add the whole numbers together and add the fractions together. To add the fractions we need common denominators. Now that we have common denominators, we can add the numerators and leave the denominator the same.

Explanation: To add complex fractions, convert the numerators and denominators into single fractions, then simplify. Start by finding the lowest common denominator in both the numerator and denominator of the complex fraction. Add fractions with like denominators.

If the whole number is odd, divide it in half and round the decimal down to the nearest whole number. Add the numerator and denominator of the fraction together to get the new numerator. Multiply the old denominator by 2 to get the new denominator. For example, to halve 3 1/2, divide 3 / 2 = 1.5 (round down to 1).

Procedure:To find equivalent fractions, multiply the numerator AND denominator by the same nonzero whole number. This procedure is used to solve example 4. You can multiply the numerator and the denominator of a fraction by any nonzero whole number, as long as you multiply both by the same whole number!

To do this, give the whole number a denominator of 1. Convert to fractions of like denominators. The original fraction's denominator is also the least common denominator (LCD) of the two fractions. Multiply the top and bottom of the "whole number fraction" by this number so the fractions have the same denominator.

The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
