Question

-3(минус 3 целых) 5/21:1(целую) 22/63+1(целая) 13/35:1(целую) 1/56

Answer 1

будет 19753 целую 1/68

Answer 2

To simplify the given expression, let's perform the calculations step by step:

1. Start with -3(minus 3 whole): -3 * (-3) = 9

2. Next, perform division: 5/21 ÷ 1(whole): 5/21 ÷ 1 = 5/21

3. Continue with addition: 22/63 + 1(whole): 22/63 + 1 = 22/63 + 63/63 = (22 + 63) / 63 = 85/63

4. Now, divide: 13/35 ÷ 1(whole): 13/35 ÷ 1 = 13/35

5. Finally, subtraction: 9 - 5/21 - 85/63 - 13/35 - 1/56:

   To perform the subtraction, we need to find a common denominator for all fractions involved. The least common multiple (LCM) of 21, 63, 35, and 56 is 504.

   9 - (5/21 * 24/24) - (85/63 * 8/8) - (13/35 * 16/16) - (1/56 * 9/9)

   9 - 120/504 - 680/504 - 208/504 - 9/504

   Now, combine the fractions:

   (9 - 120 - 680 - 208 - 9) / 504

   (-1008) / 504 = -2

The simplified expression is -2.
