Answer 2

It seems like there might be some non-standard characters and extra text in your input, making it difficult to interpret. If you meant to perform the subtraction of 7 4/5 minus 3 1/4, you can do it as follows:

First, convert the mixed numbers into improper fractions: 7 4/5 = 7 + 4/5 = 35/5 + 4/5 = 39/5 3 1/4 = 3 + 1/4 = 12/4 + 1/4 = 13/4

Now, subtract the fractions: (39/5) - (13/4)

To subtract fractions, you need a common denominator, which in this case is 20. So, you'll need to find equivalent fractions with a common denominator of 20:

(39/5) * (4/4) = 156/20 (13/4) * (5/5) = 65/20

Now, subtract the fractions with the common denominator:

(156/20) - (65/20) = (156 - 65) / 20 = 91/20

So, the result of 7 4/5 - 3 1/4 is 91/20, which can also be expressed as a mixed number, which is approximately 4 11/20.
