Question

(16 1/2-9 7/9)×18/33+0.5

Answer 1

Ответ:

(16 1/2 - 13 7/9) * 18/33 + 2,2 * (8/33 - 1/11) + 2/11 = 2

1) 16 1/2 - 13 7/9 = 16 9/18 - 13 14/18 = 15 27/18 - 13 14/18 = 2 13/18

2) 2 13/18 * 18/33 = 49/18 * 18/33 = 49/33 = 1 16/33

3) 8/33 - 1/11 = 8/33 - 3/33 = 5/33

4) 2,2 * 5/33 = (2,2 * 5)/33 = 11/33

5) 1 16/33 + 11/33 = 1 27/33

6) 1 27/33 + 2/11 = 1 27/33 + 6/33 = 1 33/33 = 2

Answer 2

Let's solve the expression step by step.

First, let's convert the mixed numbers into improper fractions:

16 1/2 = 33/2 9 7/9 = 88/9

Now, the expression becomes:

(33/2 - 88/9) * 18/33 + 0.5

To simplify the fractions, find a common denominator and convert them:

Common denominator for 2 and 9 is 18.

33/2 = 297/18 88/9 = 176/18

Now the expression becomes:

(297/18 - 176/18) * 18/33 + 0.5

Simplify the numerator first:

(121/18) * 18/33 + 0.5

Cancel out common factors:

121/33 + 0.5

Now, add the fractions:

121/33 = 3 and 10/33

Therefore, the expression becomes:

3 + 10/33 + 0.5

Now add the whole numbers and fractions separately:

3 + 0.5 = 3.5

10/33 cannot be simplified further.

So the final result is:

3.5 + 10/33
