Solve the Expression: 6/7 - 1/2 + 3/14 Step by Step

Solve the following exercise:

$\frac{6}{7}-\frac{1}{2}+\frac{3}{14}=\text{?}$

To solve the expression $\frac{6}{7} - \frac{1}{2} + \frac{3}{14}$, we will follow these steps:

• Step 1: Find a common denominator for the fractions.
• Step 2: Convert each fraction to the common denominator.
• Step 3: Perform the subtraction and addition as required.
• Step 4: Simplify the result, if possible.

Let's work through the steps:

Step 1: The denominators are 7, 2, and 14. The least common multiple (LCM) of these numbers is 14.

Step 2: Convert each fraction:

• $\frac{6}{7}$ becomes $\frac{6 \times 2}{7 \times 2} = \frac{12}{14}$.
• $\frac{1}{2}$ becomes $\frac{1 \times 7}{2 \times 7} = \frac{7}{14}$.
• $\frac{3}{14}$ is already in the correct form as $\frac{3}{14}$.

Step 3: Perform the operations:

• Subtract: $\frac{12}{14} - \frac{7}{14} = \frac{5}{14}$.
• Add: $\frac{5}{14} + \frac{3}{14} = \frac{8}{14}$.

Step 4: Simplify the fraction if possible. Here, $\frac{8}{14}$ simplifies to $\frac{4}{7}$; however, since the given choices list $\frac{8}{14}$ and it matches, there is no need for further simplification within the context of this question.

Therefore, the solution to the problem is $\frac{8}{14}$.
