Answer 1

1)
11/4*(-2/3)=-1 5/6
-1 5/6*(-4/11)=2/3
2)
-50/21*2/13=-100/273
-21/50*(-100/273)=2/13
3)
-12/19*26/15=-1 3/5
15/26*(-8/5)=-12/13

Answer 2

Calculating the Expression

To solve the given expression, we can follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

The given expression is: 11/4*(-2/3)*(-4/11) + -21/50*(-50/21*2/13) + 15/26*(-12/19*26/15)

Let's calculate it step by step.

1. Calculate the first part: 11/4*(-2/3)*(-4/11)

This simplifies to: = 11/4 * 2/3 * 4/11 = (11 * 2 * 4) / (4 * 3 * 11) = 88 / 132 = 2/3

2. Calculate the second part: -21/50*(-50/21*2/13)

This simplifies to: = -21/50 * (-100/273) = 21/50 * 100/273 = (21 * 100) / (50 * 273) = 2100 / 13650 = 14/91

3. Calculate the third part: 15/26*(-12/19*26/15)

This simplifies to: = 15/26 * (-312/285) = -4680 / 7410 = -1560 / 2470 = -780 / 1235 = -156/247

Final Result

Adding the three calculated parts together: 2/3 + 14/91 - 156/247 = (2*247 + 14*3 - 156*91) / (3*91*247) = (494 + 42 - 14256) / 6783 = -13720 / 6783

So, the final result of the given expression is -13720/6783.
