Question

15 1/6 : x + 0,13y при x = 18,2 и y = 7 1/13 (64 1/11 : 4 6/11 - 0,8):9,5 + 108,2

Answer 1

15ц1/6 : 18ц2/10 + 13/100*7ц1/13 = 91/6*10/182 + 13/100*92/13 = 5/6 + 92/100 = 500/600 + 552/600=1052/600=576/300=192/100=1,92

=(705/11 * 11/50 - 8/10):95/10 + 108,2 = (141/10-8/10)*10/95+108,2=
=133/10*10/95+108,2 = 133/95+108,2=1ц38/95+108,2=1,4+108,2=109,6

Answer 2

Let's break down the expression step by step:

1. Evaluate x and y: Given: x = 18.2, y = 7 1/13 (which can be converted to an improper fraction as 92/13).

2. Evaluate the first expression: 15 1/6 : x + 0.13y Convert 15 1/6 to an improper fraction: (15 * 6 + 1) / 6 = 91 / 6 Evaluate: (91 / 6) / 18.2 + 0.13 * (92 / 13)

3. Evaluate the second expression: 64 1/11 : 4 6/11 - 0.8 Convert 64 1/11 to an improper fraction: (64 * 11 + 1) / 11 = 705 / 11 Convert 4 6/11 to an improper fraction: (4 * 11 + 6) / 11 = 50 / 11 Evaluate: (705 / 11) / (50 / 11) - 0.8

4. Divide the result from step 3 by 9.5: Result from step 3 / 9.5

5. Add 108.2 to the result from step 4: Result from step 4 + 108.2

Now, let's perform the calculations:

1. x = 18.2, y = 7 1/13 (which is 92/13)
2. (91 / 6) / 18.2 + 0.13 * (92 / 13) ≈ 0.9517 + 1.1388 ≈ 2.0905
3. (705 / 11) / (50 / 11) - 0.8 ≈ 7.8667 - 0.8 ≈ 7.0667
4. 7.0667 / 9.5 ≈ 0.7439
5. 0.7439 + 108.2 ≈ 108.9439

So, the final result of the given expression is approximately 108.9439.
