Question

3 1/3 - 2,526 1/11-5,7​

Answer 1

Ответ и пошаговое объяснение:

3 1/3 - 2,5  =

= 3 2/6 - 2 3/6 =

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

= 8/6 - 3/6 =

= 5/6

                                                               

26 1/11 - 5,7​ =

= 26 1/11 - 5 7/10 =

= 26 10/110 - 5 77/110 =

= 21 + ( 10/110 - 77/110 ) =

= 20 + ( 120/110 - 77/110 ) =

= 20 43/110

Answer 2

To solve this expression, we need to perform the subtraction step by step. Let's start by converting all the numbers to improper fractions for easier computation:

3 1/3 = 3 + 1/3 = 10/3 2,526 1/11 = 2,526 + 1/11 = 2,637/11 5,7 = 5 + 7/10 = 57/10

Now, the expression becomes:

10/3 - 2,637/11 - 57/10

To perform the subtraction, we need to find a common denominator. The common denominator for 3, 11, and 10 is 330. Now, we'll convert each fraction to have a denominator of 330:

(10/3) * (110/110) = 110/330 (2,637/11) * (30/30) = 28907/330 (57/10) * (33/33) = 1881/330

Now, the expression becomes:

110/330 - 28907/330 - 1881/330

To combine the fractions, we subtract the numerators while keeping the common denominator:

(110 - 28907 - 1881)/330

Calculating the numerator:

110 - 28907 - 1881 = -30778

The final fraction is:

-30778/330

Now, this fraction can be simplified. The greatest common divisor (GCD) between the numerator and denominator is 2:

-30778 ÷ 2 = -15389 330 ÷ 2 = 165

So, the simplified fraction is:

-15389/165

Now, if we want to express this as a mixed number (whole number and fraction), we divide the numerator by the denominator:

-15389 ÷ 165 = -93 with a remainder of -44

The mixed number is:

-93 - 44/165

Therefore, the result of the expression is approximately -93 44/165.

Answer 3

To subtract the numbers, let's first convert the mixed numbers to improper fractions and then perform the subtraction.

Step 1: Convert mixed numbers to improper fractions. 3 1/3 can be written as (3 * 3 + 1) / 3 = 10/3 2,526 1/11 can be written as (2,526 * 11 + 1) / 11 = 27787/11 5,7 can be written as 5 + 7/10 = 5 + 7/10 = 5 7/10 = (5 * 10 + 7) / 10 = 57/10

Step 2: Perform the subtraction. 10/3 - 27787/11 - 57/10

To perform the subtraction, we need to find a common denominator for the three fractions. The common denominator for 3, 11, and 10 is 330 (3 * 11 * 10).

Now, let's convert each fraction to have a denominator of 330.

(10/3) * (110/110) = 110/330 (27787/11) * (30/30) = 83361/330 (57/10) * (33/33) = 1881/330

Now, the subtraction becomes:

110/330 - 83361/330 - 1881/330

Subtract the numerators:

(110 - 83361 - 1881) / 330 = -85232 / 330

The result is -85232/330, which can be simplified further:

-85232/330 = -42616/165

So, the final result of the subtraction is -42616/165.
