Answer: 1

Step-by-step explanation:  1 Find the Least Common Denominator (LCD) of \frac{1}{4}, \frac{1}{3}, \frac{1}{6}, \frac{1}{8}, \frac{1}{8}

Method 1: By Listing Multiples

List out all multiples of each denominator, and find the first common one.

Multiples of 4 : 4, 8, 12, 16, 20, 24, ...  

Multiples of 3 : 3, 6, 9, 12, 15, 18, 21, 24, ...  

Multiples of 6 : 6, 12, 18, 24, ...  

Multiples of 8 : 8, 16, 24, ...  

Multiples of 8 : 8, 16, 24, ...  

Therefore, the LCD is 2424.

Method 2: By Prime Factors

List all prime factors of each denominator, and find the union of these primes.

Prime Factors of 4 : 2, 2

Prime Factors of 3 : 3

Prime Factors of 6 : 2, 3

Prime Factors of 8 : 2, 2, 2

Prime Factors of 8 : 2, 2, 2

Therefore, the LCD is 2\times 2\times 2\times 3=242×2×2×3=24.

LCD = 2424

2 Make the denominators the same as the LCD.

\frac{1\times 6}{4\times 6}+\frac{1\times 8}{3\times 8}+\frac{1\times 4}{6\times 4}+\frac{1\times 3}{8\times 3}+\frac{1\times 3}{8\times 3}

3 Simplify. Denominators are now the same.

4 Join the denominators.

\frac{6+8+4+3+3}{24}

5 Simplify.

\frac{24}{24}
