Question

-3 8/31+4,1+(-6)+2,9

Answer 1

-3 8/31+4,1=-101/31+41/10=-1010/310+1271/310=261/310

261/310+(-6)=261/310-6=261/310-1860/310=-1599/310

-1599/310+2,9=-1599/310+29/10=-1599/310+899/310=-700/310=-70/31=-2 8/31

Answer 2

To calculate the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Now, let's solve the expression step by step:

1. -3 + 8/31 + 4.1 + (-6) + 2.9

2. -3 + 0.258 + 4.1 + (-6) + 2.9 (divide 8 by 31)

3. -3 + 0.258 + 4.1 - 6 + 2.9 (add 8/31 to -3)

4. 4.358 - 6 + 2.9 (add 4.1 to 0.258)

5. -1.642 + 2.9 (subtract 6 from 4.358)

6. 1.258 (add 2.9 to -1.642)

The final result is approximately 1.258.
