Solve Fraction Addition: 3/9 + 1/9 Step-by-Step

Question

Solve the following exercise:

$\frac{3}{9}+\frac{1}{9}=\text{?}$

00:00 Solve

00:03 Let's divide our one rectangle into 9 parts

00:06 Let's color 3 parts (3 ninths) in red

00:11 Let's color one part in green

00:14 Let's combine the parts and get the numerator result

00:17 And this is the solution to the question

To solve this problem, we'll follow a straightforward approach to adding fractions with like denominators:

Consider the fractions given: $\frac{3}{9}$ and $\frac{1}{9}$ .

Step 1: Since both fractions have the same denominator, we add their numerators: $3 + 1 = 4$ .
Step 2: Keep the denominator the same: 9.
Step 3: Resulting in the fraction: $\frac{4}{9}$ .

The computation confirms that the addition of these fractions results in $\frac{4}{9}$ .

Therefore, the correct solution to the problem is $\frac{4}{9}$ , which corresponds to choice 3.

$\frac{4}{9}$
