A Definition and its Significance

In mathematics, a fraction represents a part of a whole. The top number, known as the numerator, tells how many parts you have. The bottom number, called the denominator, represents the total number of parts. Fractions with like denominators are fractions that have the same “part-dividing” value-in other words, their bottom numbers are the same.

Adding fractions with like denominators is a crucial skill in everyday life, not just in the kitchen. From following recipes to calculating construction measurements, it’s essential for accurate computations. Now, let’s dive into the steps.

Unleashing the Power of Like Denominators

1. Keep the Denominator Constant: The key to adding fractions with the same denominator is to keep that denominator in place. It serves as a common ground, uniting your fractions.

2. Add the Numerators Cheerfully: Next, you’ll focus on the top numbers-the numerators. Simply add them together as if you were solving any other math problem. Remember, it’s the numerators that show you the size of the fractions you’re adding.

3. Voila! A New Fraction is Born: The result you get from adding the numerators becomes the new numerator for your final fraction. The denominator remains the same, since we’re dealing with like denominators.

Let’s Drill with Examples

Let’s say you need to add 1/3 and 2/3. Following the steps above, you keep the denominator 3 and add the numerators: 1 + 2 = 3. So, 1/3 + 2/3 = 3/3 or simply 1.

Another example: 5/7 + 2/7. Here, too, you keep the denominator 7 and add the numerators: 5 + 2 = 7. Thus, 5/7 + 2/7 = 7/7 or 1.
