Answer 3

Adding Fractions:

To solve the addition of fractions 2/5 + 4/4, we need to find a common denominator and then add the fractions together.

Finding a Common Denominator:

The common denominator is the least common multiple of the denominators. In this case, the denominators are 5 and 4. The least common multiple of 5 and 4 is 20.

Converting Fractions to Have the Common Denominator:

To add the fractions, we need to express both fractions with the common denominator of 20.

Converting 2/5 to have a denominator of 20: - Multiply the numerator and denominator by 4: (2 * 4) / (5 * 4) = 8/20

Converting 4/4 to have a denominator of 20: - The fraction 4/4 is already in terms of 20, as 4 * 5 = 20.

Adding the Fractions:

Now that both fractions have the same denominator, we can add them together: 8/20 + 4/20 = 12/20

Simplifying the Result:

The fraction 12/20 can be simplified by finding the greatest common divisor of the numerator and denominator, which is 4. Dividing both the numerator and denominator by 4 gives us the simplified fraction: 12/20 = 3/5

So, 2/5 + 4/4 = 3/5.
