Answer 1

Ответ:

1) 30026-29796 =230

276 ×775=213900

213900:230= 930

2) 7294:14 =521

12960:27= 480

521+480= 1001

1001:91 =11

3) 131364:41 =3204

19000:25 = 760

3204-760=2444

2444:52= 47

Answer 2

Let's solve each of these expressions step by step:

1. $\frac{276 \times 775}{30026 - 29796}$

   First, let's calculate the denominator: $30026 - 29796 = 230$

   Now we can substitute this value into the expression: $\frac{276 \times 775}{230}$

   Now calculate the numerator: $276 \times 775 = 213900$

   Finally, divide the numerator by the denominator: $\frac{213900}{230} \approx 930$

So, $\frac{276 \times 775}{30026 - 29796} \approx 930$

2. $\frac{\frac{7294}{14} + \frac{12960}{27}}{91}$

   Calculate the values within the inner parentheses: $\frac{7294}{14} \approx 521.0$ $\frac{12960}{27} \approx 480.0$

   Add these two results: $521.0 + 480.0 = 1001.0$

   Finally, divide the sum by 91: $\frac{1001.0}{91} \approx 11.0$

So, $\frac{\frac{7294}{14} + \frac{12960}{27}}{91} \approx 11.0$

3. $\frac{\frac{131364}{41} - \frac{19000}{25}}{52}$

   Calculate the values within the inner parentheses: $\frac{131364}{41} \approx 3204.0$ $\frac{19000}{25} \approx 760.0$

   Subtract the second value from the first: $3204.0 - 760.0 = 2444.0$

   Finally, divide the result by 52: $\frac{2444.0}{52} \approx 46.923$

So, $\frac{\frac{131364}{41} - \frac{19000}{25}}{52} \approx 46.923$

Please note that these calculations have been rounded to a reasonable number of decimal places.
