Answer 3

To add and subtract mixed numbers, you should first find a common denominator for the fractions involved. In this case, the common denominator is 25, which is the least common multiple of the denominators in the fractions.

Now, let's perform the calculations step by step:

1. Add the fractions: 14/25 + 7/25 + 5/15 = (14/25 + 7/25) + (5/15)

   First, add 14/25 and 7/25: (14/25 + 7/25) = 21/25

   Now, add 21/25 to 5/15. To do this, we need to convert 5/15 to an equivalent fraction with a denominator of 25: 5/15 = (5/15) * (5/5) = 25/75

   Now, add 21/25 and 25/75: (21/25) + (25/75) = (63/75) + (25/75) = 88/75

2. Now, let's add and subtract the whole numbers: 18 + 12 - 21 + 6 = 18 + 12 - 21 + 6 = 15

3. Combine the results from steps 1 and 2: 88/75 + 15

To add a fraction to a whole number, you need to convert the whole number to a fraction with the same denominator (in this case, 75): 15 = 15/1

Now, add 88/75 and 15/1: (88/75) + (15/1)

To add these fractions, find a common denominator, which is 75: (88/75) + (15/1) = (88/75) + (15/1) * (75/75)

Now, both fractions have a denominator of 75: (88/75) + (1125/75) = (88 + 1125) / 75

Finally, simplify the fraction: (88 + 1125) / 75 = 1213/75

So, the result is 1213/75. You can further simplify this fraction if needed.
