Answer 2

To add these three mixed numbers, you can follow these steps:

1. Convert each mixed number to an improper fraction.
2. Find a common denominator for the fractions.
3. Add the fractions together.
4. If needed, simplify the resulting fraction.

Let's do the calculations:

1. Convert mixed numbers to improper fractions:

   • 3/5 = 3/5
   • 17 1/10 = (10 * 17 + 1)/10 = 171/10
   • 14 13/30 = (30 * 14 + 13)/30 = 433/30

2. Find a common denominator for the fractions. In this case, the common denominator is 30, which is a multiple of 5 and 10.

3. Add the fractions:

   3/5 + 171/10 + 433/30

4. Now, add the fractions together. First, you need to make all the fractions have a common denominator of 30:

   • 3/5 is already in terms of 30 (multiply numerator and denominator by 6).
   • 171/10 needs to be converted to 30 by multiplying both numerator and denominator by 3 (171/10 * 3/3 = 513/30).
   • 433/30 is already in terms of 30.

Now, add the fractions:

3/5 + 513/30 + 433/30

Combine the fractions:

(3/5) + (513/30) + (433/30) = (3/5) + (513/30 + 433/30)

Now, add the fractions in the parentheses:

(3/5) + (946/30)

To add these fractions, you need a common denominator of 30:

(3/5) + (946/30 * 5/5) = (3/5) + (4730/30)

Now, they have the same denominator, and you can add them:

(3/5) + (4730/30) = (3/5) + (4730/30) = (3/5) + (1576/10)

Now, make both fractions have a common denominator of 10:

(3/5 * 2/2) + (1576/10) = (6/10) + (1576/10)

Now, add the fractions:

(6/10) + (1576/10) = 1582/10

Finally, simplify the fraction:

1582/10 = 791/5

So, the result of the addition is 791/5.
