Question

-3 2/6-(-1 1/2)+1,5+0-3 2/6​

Answer 1

Ответ:

-3 2/3

Пошаговое объяснение:

1) -3 2/6 - (-1 1/2) = -3 2/6 + 1 1/2 = -3 2/6 + 1 3/6 = -2 8/6 + 1 3/6 = -1 5/6

2) -1 5/6 + 1,5 = -1 5/6 + 1 5/10 = -1 25/30 + 1 15/30 = -10/30 = -1/3

3) -1/3 + 0 = -1/3

4) -1/3 - 3 2/6 = -1/3 - 3 1/3 = -3 2/3

Пошаговое объяснение:

-3 2/6-(-1 1/2)+1,5+0-3 2/6​= -3 2/6 -  3 2/6 +1 1/2 +1,5= - 6 4/6 + 1 1/2 + 1 1/2=

= - 6 2/3 + 2 2/2=-6 2/3 + 3 = - (6 2/3 -3)= - 3 2/3

Answer 3

To simplify the expression, we can follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In your expression, we have addition and subtraction, so we'll start by performing those operations from left to right:

-3 2/6 - (-1 1/2) + 1.5 - 3 2/6

First, we'll deal with the subtraction of fractions: -3 2/6 - (-1 1/2) = -3 2/6 + 1 1/2

Now, let's add these fractions: -3 2/6 + 1 1/2 = -3 2/6 + 3/2

Next, convert both fractions to have a common denominator of 6: -3 2/6 + (3/2 * 3/3) = -3 2/6 + 9/6

Now that the fractions have the same denominator, we can add them: -3 2/6 + 9/6 = -3 + 9/6 - 2/6

Combine the whole numbers: -3 + 9/6 - 2/6 = -3 + 7/6

Now, let's add the decimal 1.5 and subtract 3 2/6:

-3 + 7/6 + 1.5 - 3 2/6

Next, convert 1.5 into a fraction with a common denominator of 6: 1.5 = 3/2 (when written as a fraction with a denominator of 2)

Now, add 3/2 to 7/6: 7/6 + 3/2 = (7/6 * 1/2) + (3/2 * 3/3) = 7/12 + 9/6

Again, convert both fractions to have a common denominator of 12: 7/12 + 9/6 = 7/12 + (9/6 * 2/2) = 7/12 + 18/12

Now that the fractions have the same denominator, we can add them: 7/12 + 18/12 = (7 + 18)/12 = 25/12

Now, subtract 3 2/6 from this result: -3 + 25/12

To subtract a mixed number, you can convert it into a fraction with the same denominator as 12: -3 = -36/12

Now, subtract -36/12 from 25/12: -36/12 + 25/12 = (-36 + 25)/12 = -11/12

So, the simplified result is -11/12.
