What is the sum of [tex]\frac{7}{12}[/tex] and [tex]\frac{18}{12}[/tex]?

A. [tex]\frac{12}{25}[/tex]
B. [tex]\frac{11}{12}[/tex]
C. [tex]1 \frac{1}{24}[/tex]
D. [tex]2 \frac{1}{12}[/tex]

Answer :

To find the sum of [tex]\(\frac{7}{12}\)[/tex] and [tex]\(\frac{18}{12}\)[/tex], we follow these steps:

1. Identify the Denominators:
Both fractions have the same denominator, which is 12. This means we can easily add them without needing to find a common denominator.

2. Add the Numerators:
Since the denominators are the same, add the numerators:
[tex]\[
7 + 18 = 25
\][/tex]

3. Write the Sum:
Put the sum of the numerators over the common denominator:
[tex]\[
\frac{25}{12}
\][/tex]

4. Simplify the Fraction (if necessary):
Check if the fraction can be simplified. In this case, [tex]\(\frac{25}{12}\)[/tex] is already in its simplest form.

5. Convert to a Mixed Number:
If you want to express [tex]\(\frac{25}{12}\)[/tex] as a mixed number, divide 25 by 12:
- 25 divided by 12 is 2 with a remainder of 1.
- Thus, [tex]\(\frac{25}{12}\)[/tex] can be written as [tex]\(2 \frac{1}{12}\)[/tex].

Thus, the sum of [tex]\(\frac{7}{12}\)[/tex] and [tex]\(\frac{18}{12}\)[/tex] is [tex]\(2 \frac{1}{12}\)[/tex].

The correct answer is option D. [tex]\(2 \frac{1}{12}\)[/tex].
