We find the least common multiple of the denominators: To do that, we could try the divisibility of the multiples of 88 by 76 - 88 isn't divisible by 76, 88 * 2 = 176 isn't divisible by 76... But since the numbers 76 and 88 are relatively large, this method would take a lot of time. Instead, we find the LCM by the prime factorization of ...

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

How to Add and Subtract Fractions When the Denominators are Different. This is a bit tricky, but you'll think it's easy once you get used to it! Let's try this: 1/2 + 1/3. The main rule of this game is that we can't do anything until the denominators are the same! We need to find something called the least common denominator ...

Like fractions are fractions with the same denominator. You can add and subtract like fractions easily - simply add or subtract the numerators and write the sum over the common denominator. Before you can add or subtract fractions with different denominators, you must first find equivalent fractions with the same ...
