What is the first rule of adding and subtracting fractions?

To add or subtract fractions they must have the same denominator (the bottom value). If the denominators are already the same then it is just a matter of either adding or subtracting the numerators (the top value). If the denominators are different then a common denominator needs to be found.

What are the steps to add and subtract fractions with different denominators?

Adding and Subtracting Fractions with Unlike Denominators

  1. STEP ONE: Get a common denominator.
  2. STEP TWO: Add or subtract the numerators.
  3. STEP THREE: Simplify the result if needed. Notice that 3/27 can be simplified, since the numerator and denominator are both divisible by 3.
  4. And that’s all there is to it! Final Answer:

How do you explain 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)

What are the rules for subtracting fractions?

There are 3 simple steps to subtract fractions

  • Make sure the bottom numbers (the denominators) are the same.
  • Subtract the top numbers (the numerators). Put the answer over the same denominator.
  • Simplify the fraction (if needed).

How do you add and subtract fractions with the same denominator?

If the denominators are the same, then it’s pretty easy: just add or subtract the numerators , and write the result over the same denominator. You may get an answer which is not in lowest terms , even if the fractions you were adding and subtracting both were. In this case, you have to reduce the fraction .

How to add and subtract mixed fractions?

There are two methods for the addition and subtraction of mixed fraction. Addition and subtraction of like mixed fraction. Addition and subtraction of unlike mixed fraction. Example 5: 3 3/4 + 2 2/4 =? Example 6: 3 3/4 + 2 2/4 =? In Unlike mixed fraction the denominator of the fractional part is different which needs to be made the same using LCM.

What is the addition and subtraction of Unlike fractions?

Addition and Subtraction of Unlike Fraction The fractions which have the different denominators are known as unlike fractions. For addition and subtraction of fraction the denominators of the fraction should be the same. So we need to make them the same by taking LCM of the denominators.

How can I Help my Child with addition of fractions?
