Answer 1

Найдём обще длитела это будешь 18
(3*15-2*25+6*41-9*31)=
(45-50+246-279)=
(-5-33)=-38

Answer 2

1 5/6-2 5/9=1 15/18-2 10/18=-13/18
-13/18+4 1/3=-13/18+4 6/18=3 11/18
3 11/18-3 1/9=3 11/18-3 9/18=2/18=1/9

Answer 3

To solve the expression, let's first convert all the fractions to have a common denominator:

1 5/6 - 25/9 + 41/3 - 31/2

The common denominator for these fractions is 18. Multiplying the numerator and denominator of each fraction accordingly, we get:

(1 * 18 + 5) / 6 - (25 * 2) / 9 + (41 * 6) / 3 - (31 * 9) / 2

(18 + 5) / 6 - (50) / 9 + (246) / 3 - (279) / 2

23 / 6 - 50 / 9 + 246 / 3 - 279 / 2

To add or subtract fractions, we need a common denominator. In this case, the common denominator is 18. We can rewrite each fraction with this denominator:

(23 * 3) / (6 * 3) - (50 * 2) / (9 * 2) + (246 * 6) / (3 * 6) - (279 * 9) / (2 * 9)

69 / 18 - 100 / 18 + 1476 / 18 - 2511 / 18

Now that the fractions have the same denominator, we can combine the numerators:

(69 - 100 + 1476 - 2511) / 18

-1066 / 18

Simplifying the expression gives us:

-59 1/6

Therefore, 1 5/6 - 25/9 + 41/3 - 31/2 equals -59 1/6.
