Answer 2

To add these fractions together, you need to find a common denominator. In this case, the least common denominator is 100. Here's how you can do it step by step:

1. To make the denominators all equal to 100, you can multiply the first fraction by 5/5, the second fraction by 4/4, and the third fraction by 10/10. This doesn't change the value of the fractions but gives them common denominators.

2. So, the fractions become:

   • (3/20) * (5/5) = 15/100
   • (4/25) * (4/4) = 16/100
   • (3/10) * (10/10) = 30/100

3. Now that the fractions have the same denominator, you can add them together: (15/100) + (16/100) + (30/100) = (15 + 16 + 30) / 100 = 61/100

So, the result is 61/100.
