Math Problem Statement

Evaluate the expression shown below and write your answer as a fraction in simplest form: 6/5 + 12/35

Solution

The expression provided is:

65+1235\frac{6}{5} + \frac{12}{35}

Step 1: Find the Least Common Denominator (LCD)

The denominators are 5 and 35. The LCD of 5 and 35 is 35.

Step 2: Convert each fraction to have a denominator of 35

For 65\frac{6}{5}, multiply both the numerator and the denominator by 7 to get:

65=6×75×7=4235\frac{6}{5} = \frac{6 \times 7}{5 \times 7} = \frac{42}{35}

Now, the fractions are:

4235+1235\frac{42}{35} + \frac{12}{35}

Step 3: Add the fractions

Since the denominators are the same, add the numerators:

42+1235=5435\frac{42 + 12}{35} = \frac{54}{35}

Step 4: Simplify if possible

5435\frac{54}{35} is already in its simplest form because 54 and 35 have no common factors other than 1.

Final Answer:

5435\frac{54}{35}
