Question

1)-6,6+4/5+(1 целая 2/3)+3,4

Answer 1

-33/5+4/5+2/3+17/5

-26/15

Answer 2

To solve the expression, let's 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)

The expression is:

-6 + 6 + 4/5 + (1 целая 2/3) + 3.4

Now, let's simplify it step-by-step:

1. -6 + 6 = 0
2. 4/5 remains the same.
3. (1 целая 2/3) can be converted to an improper fraction: 1 целая 2/3 = 1 + 2/3 = 3/3 + 2/3 = 5/3
4. Adding 3.4 remains the same.

The expression now becomes:

0 + 4/5 + 5/3 + 3.4

Next, we need to find a common denominator to add the fractions:

The common denominator for 4/5 and 5/3 is 15.

Now, let's rewrite the expression with the common denominator:

0 + (4/5 * 3/3) + (5/3 * 5/5) + 3.4

Simplifying further:

0 + 12/15 + 25/15 + 3.4

Now, add the fractions:

12/15 + 25/15 = 37/15

The expression becomes:

0 + 37/15 + 3.4

Finally, add the whole numbers and the decimal:

0 + 37/15 + 3.4 ≈ 3.4666667 (rounded to seven decimal places)

So, the result of the expression is approximately 3.4666667.
