Answer 2

$26\frac{18}{91}-27\frac{8}{21}-26\frac{18}{91}-4\frac{18}{35}=-27\frac{40}{105}-4\frac{54}{105}=-31\frac{94}{105}$

Answer 3

To solve this expression, let's perform the calculations step by step:

Step 1: Convert all mixed numbers to improper fractions. 26 целых 18/91 = (26 * 91 + 18)/91 = 2414/91 27 целых 8/21 = (27 * 21 + 8)/21 = 565/21 4 целых 18/35 = (4 * 35 + 18)/35 = 158/35

Step 2: Perform the subtraction. (2414/91) - (565/21) - (2414/91) - (158/35)

Step 3: Find a common denominator. The common denominator for 91 and 21 is 91 * 21 = 1911. The common denominator for 91, 21, and 35 is 91 * 21 * 35 = 67455.

Step 4: Rewrite each fraction with the common denominator. (2414/91) becomes (2414 * 21)/67455 = 50814/67455 (565/21) becomes (565 * 91)/67455 = 51415/67455 (2414/91) becomes (2414 * 21)/67455 = 50814/67455 (158/35) becomes (158 * 91 * 21)/67455 = 313758/67455

Step 5: Perform the subtraction. 50814/67455 - 51415/67455 - 50814/67455 - 313758/67455

Step 6: Combine like terms. (-51415 - 50814 - 313758)/67455 = -415987/67455

So, the result of the expression is -415987/67455.
