Answer: 5/8 + 2/3 = \frac{31}{24}
Step-by-Step Solution
Step 1 Identify the Fractions

We need to add two fractions: 5/8 and 2/3

To add fractions, they must have the same denominator (bottom number).

\frac{5}{8} + \frac{2}{3} = ?
Step 2 Find the Least Common Denominator (LCD)

The denominators are different (8 and 3), so we need to find a common denominator.

The LCD is the smallest number that both 8 and 3 divide into evenly.

LCD = 8 × 3 = 24

\text{LCD}(8, 3) = 24
Step 3 Convert First Fraction

Multiply 5/8 to get denominator of 24:

Multiply both top and bottom by 3

\frac{5}{8} = \frac{5 \times 3}{8 \times 3} = \frac{15}{24}
Step 4 Convert Second Fraction

Multiply 2/3 to get denominator of 24:

Multiply both top and bottom by 8

\frac{2}{3} = \frac{2 \times 8}{3 \times 8} = \frac{16}{24}
Step 5 Add the Fractions

Now both fractions have the same denominator (24).

Add the numerators: 15 + 16 = 31

\frac{15}{24} + \frac{16}{24} = \frac{15 + 16}{24} = \frac{31}{24}
Step 6 Convert to Mixed Number

Since 31 > 24, we can write this as a mixed number.

31 ÷ 24 = 1 remainder 7
\frac{31}{24} = 1\frac{7}{24}
