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

Answer 1

Ответ:   2.

Объяснение:

(16 1/2-13 7/9)*18/33+2.2(8/33-1/11)+2/11=2.

1) 16 1/2-13 7/9 = 3 (1/2-7/9) = 3 (9/18 - 14/18)=2 ((18+9)/18-14/18)=2  13/18;

2)  2 13/18*18/33 = 49/18*18/33 =49/33;

3)  8/33-1/11 = 8/33-3/33=5/33;

4)  5/33*2.2 = 5/33*22/10= 1/3;

5)  49/33 +1/3+2/11=49/33+11/33+6/33=(49+11+6)/33=66/33=2.

Answer 2

To solve the given expression, let's break it down step by step:

(16 + 1/2 - 13 + 7/9) * 18/33 + 2.2(8/33 - 1/11) + 2/11

First, let's simplify the expression inside the parentheses:

16 + 1/2 - 13 + 7/9 = 16 + 0.5 - 13 + 0.7778 ≈ 4.2778

Now, let's simplify the expression inside the second set of parentheses:

8/33 - 1/11 = (8 * 11 - 1 * 33) / (33 * 11) = (88 - 33) / 363 = 55/363 ≈ 0.1518

Next, let's substitute the simplified values back into the original expression:

4.2778 * 18/33 + 2.2 * 0.1518 + 2/11

Now, let's simplify each term:

4.2778 * 18/33 = 0.2778 * 18 ≈ 4.9996

2.2 * 0.1518 ≈ 0.334

2/11 = 0.1818

Finally, let's add up all the simplified terms:

4.9996 + 0.334 + 0.1818 ≈ 5.5154

Therefore, the value of the given expression is approximately 5.5154.

I hope this helps! Let me know if you have any further questions.
