Answer 2

Sure! Let's solve each of the expressions step by step:

1. 2 + 18/7 First, we divide 18 by 7: 18/7 = 2.5714 (rounded to four decimal places). Then, we add 2 to the result: 2 + 2.5714 = 4.5714 (rounded to four decimal places).

2. -1 + 29/1 The fraction 29/1 is equal to 29, as any number divided by 1 is the number itself. Then, we add -1 to 29: -1 + 29 = 28.

3. -4 + 32/1 Similar to the previous example, the fraction 32/1 is equal to 32. Then, we add -4 to 32: -4 + 32 = 28.

4. -7/5 + 7/4 In order to add fractions, we need a common denominator. The least common multiple of 5 and 4 is 20. We multiply -7/5 by 4/4 to get -28/20. We multiply 7/4 by 5/5 to get 35/20. Now, we can add the fractions: -28/20 + 35/20 = 7/20.

5. -8/5 + 8/7 Again, we need a common denominator to add fractions. The least common multiple of 5 and 7 is 35. We multiply -8/5 by 7/7 to get -56/35. We multiply 8/7 by 5/5 to get 40/35. Now, we can add the fractions: -56/35 + 40/35 = -16/35.

6. -6/1 + 1 The fraction -6/1 is equal to -6, as any number divided by 1 is the number itself. Then, we add -6 to 1: -6 + 1 = -5.

So, the results are:

1. 4.5714
2. 28
3. 28
4. 7/20
5. -16/35
6. -5
