How do you adding and subtracting fractions with the same denominator?

How do you adding and subtracting 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 .

What are the the rules in the addition of fractions?

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 possible)

Why is it easier to add fractions with the same denominator?

The denominator will always stay the same because the size of the equal pieces does not change when you combine the two fractions together. For example, let’s say you have 1/10 + 6/10. They have the same denominator, so they can be combined together.

What happens when the denominators are the same?

If the denominators are the same, then the fraction with the greater numerator is the greater fraction. The fraction with the lesser numerator is the lesser fraction. And, as noted above, if the numerators are equal, the fractions are equivalent.

Why does the denominator stay the same when adding fractions?

If you’re adding two fractions with a common denominator, you can combine them together by adding the numerators together (the top numbers). The denominator will always stay the same because the size of the equal pieces does not change when you combine the two fractions together.

What are the 3 rules for adding and subtracting fractions?

The steps for adding and subtracting fractions with like denominators are:

• Change mixed numbers to improper fractions if needed.
• Add or subtract the numerators.
• Write the new numerator over the denominator.
• Put the sum or difference in its lowest terms.

What are fractions with same denominators called?

The fractions with the same denominator are called like fractions..

When fractions have the same denominator Their also has the same denominator?

Fractions with the same denominators are called like fractions . To add fractions with like denominators , add the numerators , and write the sum over the denominator . We know that fractions such as 2/5, 3/5, 5/5, 7/5, 9/5, …. etc., are like fractions .

How do you explain fractions ks2?

A fraction is a number that is used to represent a whole number that has been divided into equal parts. For example, if we divide a cake into 8 equal parts and we take one piece, this would mean that 1/8 of the cake is gone and 7/8 is left. There are two parts of a fraction, the top and the bottom number.

How do you add and subtract fractions step by step?

Step 1: Find the Lowest Common Multiple (LCM) between the denominators. Step 2: Multiply the numerator and denominator of each fraction by a number so that they have the LCM as their new denominator. Step 3: Add or subtract the numerators and keep the denominator the same.
