How do you add fractions with different denominators Bitesize?

Adding fractions with different denominators

  1. Find the lowest common multiple (LCM) of the denominators.
  2. Rewrite the fractions as equivalent fractions with the same denominator.
  3. Add the numerators.
  4. Simplify where possible.

What do you have to remember when adding and subtracting fractions?

The most important thing to remember when adding or subtracting fractions is that we must have a common denominator. When the denominators are the same, all you have to do is add or subtract the numerators and keep the denominator the same.

How do you teach adding fractions?

To add fractions there are Three Simple Steps:

  1. Step 1: Make sure the bottom numbers (the denominators) are the same.
  2. Step 2: Add the top numbers (the numerators), put that answer over the denominator.
  3. Step 3: Simplify the fraction (if possible)

How do you work out fractions BBC Bitesize?

To find a fraction of an amount using a bar model :

  1. Draw a bar to represent the total amount.
  2. Split the bar into the number of parts given by the denominator.
  3. Find the value of 1 part by dividing the amount by the number of parts.
  4. Multiply the answer by the numerator.

It’s easy to add and subtract fractions when the numbers on the bottom are the same. These are called the denominators. However, sometimes the denominators are different. You use equivalent fractions to make them the same.
