Understanding Adding Subrating Fractions for 12-Year-Olds

Adding subrating fractions involves combining fractions that have different denominators. To do this, we follow a few simple steps. Let’s break it down:

Step 1: Understand What a Fraction Is

A fraction consists of two parts: the numerator (top number) and the denominator (bottom number). For example, in the fraction 1/4, 1 is the numerator and 4 is the denominator.

Step 2: Find a Common Denominator

Before adding fractions, we need to make sure the denominators are the same. This is called finding a common denominator. Let’s say we have two fractions: 1/3 and 1/6. The denominators are 3 and 6.

• The common denominator between 3 and 6 is 6.

Step 3: Adjust the Fractions

Now we need to convert the fractions so they both have the common denominator of 6:

• For 1/3, we multiply both the numerator and denominator by 2. So, 1 × 2 = 2 and 3 × 2 = 6, giving us 2/6.
• The fraction 1/6 already has the common denominator. So we keep it as 1/6.

Step 4: Add the Fractions

Now that we have 2/6 and 1/6, we can add them together. We simply add the numerators and keep the same denominator:

• Numerator: 2 + 1 = 3
• Denominator: 6

Putting them together, we get 3/6.

Step 5: Simplify the Fraction (if necessary)

Sometimes, fractions can be simplified. For 3/6, we can divide the numerator and denominator by 3:

• Numerator: 3 ÷ 3 = 1
• Denominator: 6 ÷ 3 = 2

This gives us the simplified fraction of 1/2.

Conclusion

So, when you want to add fractions with different denominators, remember: find a common denominator, adjust the fractions, add the numerators, and simplify if you can! Practice with different fractions to get the hang of it.
