Question

(2 1/3 - 1 2/3*0,75):(-4 1/3)-1/8​

Answer 1

Ответ:

-0,375

Пошаговое объяснение:

(2 1/3 -1 2/3 ·0,75)÷(-4 1/3) -1/8=-0,375

1. 1 2/3 ·0,75=5/3 ·75/100=5/3 ·3/4=5/4=1 1/4

2. 2 1/3 -1 1/4=2 4/12 -1 3/12=1 1/12

3. 1 1/12 ÷(-4 1/3)=13/12 ÷(-13/3)=13/12 ·(-3/13)=-1/4

4. -1/4 -1/8=-2/8 -1/8=-3/8=-0,375

Answer 3

Let's break down the expression step by step:

1. Start with the multiplication inside the parentheses:

   1 2/3 * 0.75 = 5/3 * 3/4 = 5/4

2. Subtract the result from 2 1/3:

   2 1/3 - 5/4

To subtract these mixed numbers, we need to find a common denominator, which is 12:

2 1/3 = 7/3 (when expressed as an improper fraction)

Now, we can subtract:

(7/3 - 5/4)

To subtract fractions with different denominators, we need to find a common denominator, which in this case is 12. So, we'll convert both fractions to have a denominator of 12:

(7/3) * (4/4) = 28/12

(5/4) * (3/3) = 15/12

Now, we can subtract:

(28/12 - 15/12) = 13/12

3. Now, let's work on the denominator of the main fraction:

   -4 1/3 = -13/3

4. Finally, divide the result from step 2 by the result from step 3 and subtract 1/8:

   (13/12) / (-13/3) - 1/8

When dividing fractions, you invert and multiply:

(13/12) * (-3/13) - 1/8

The (-13/13) cancels out to -1, so we have:

-3/12 - 1/8

Now, let's simplify the fractions:

-3/12 = -1/4

Now, we can subtract:

-1/4 - 1/8

To subtract these fractions, we need a common denominator, which is 8:

(-2/8) - (1/8) = -3/8

So, the final result is:

-3/8
