Let's follow these steps:
- Step 1: Identify the denominators of the given fractions, which are 3 and 10.
- Step 2: Calculate the least common denominator (LCD) of 3 and 10. Since 3 and 10 are co-prime, their product, 30, is the LCD.
- Step 3: Adjust the fractions to have a common denominator of 30:
- Convert 31 to a fraction with denominator 30 by multiplying the numerator and the denominator by 10:
