Answer 2

It seems like you have a mathematical expression that consists of various addition and subtraction operations involving fractions and whole numbers. Let's break it down step by step:

1. 4/5 + 23/812: To add these fractions, you need to find a common denominator, which is 812 in this case. (4/5) * (162.4/162.4) = 649.6/812 (649.6/812) + (23/812) = 672.6/812

2. 8/15 - 1210: To subtract a whole number from a fraction, convert the whole number to a fraction with the same denominator. (8/15) - (1210/1) = (8/15) - (1210/15)

Now, both fractions have the same denominator, so you can subtract the numerators: (8/15) - (1210/15) = (8 - 1210)/15 = -1202/15

3. 4/3 - 74: To subtract a whole number from a fraction, convert the whole number to a fraction with the same denominator. (4/3) - (74/1) = (4/3) - (74/3)

Now, both fractions have the same denominator, so you can subtract the numerators: (4/3) - (74/3) = (4 - 74)/3 = -70/3

4. 1/9 + 34/94: To add these fractions, you need to find a common denominator, which is 846 in this case. (1/9) * (94/94) = 94/846 (94/846) + (34/94) = (94/846) + (1444/846)

Now, both fractions have the same denominator, so you can add the numerators: (94/846) + (1444/846) = (94 + 1444)/846 = 1538/846

5. 1/6 + 1075/7: To add these fractions, you need to find a common denominator, which is 42 in this case. (1/6) * (7/7) = 7/42 (7/42) + (1075/7) = (7/42) + (18270/42)

Now, both fractions have the same denominator, so you can add the numerators: (7/42) + (18270/42) = (7 + 18270)/42 = 18277/42

6. 5/7 - 43/7: Both fractions already have the same denominator, which is 7. (5/7) - (43/7) = (5 - 43)/7 = -38/7

Now, let's simplify the results:

1. 672.6/812 simplifies to 336.3/406.
2. -1202/15 cannot be simplified further.
3. -70/3 cannot be simplified further.
4. 1538/846 simplifies to 769/423.
5. 18277/42 cannot be simplified further.
6. -38/7 cannot be simplified further.

So, the simplified results are:

1. 336.3/406
2. -1202/15
3. -70/3
4. 769/423
5. 18277/42
6. -38/7
