Answer 1

Ответ:

1) 11

2)-1 (дробь) 7/12 ................

Answer 2

Let's solve these two mathematical expressions:

1. -12 / (-1) = 12 1 / 1 = 1

So, the result of (-12,1) / (-1,1) is 12/1, which is equal to 12.

2. -12 * 3/4 - 2 * 5/12

First, simplify the fractions: -12 * 3/4 = -9 -2 * 5/12 = -5/6

Now, subtract the results: -9 - (-5/6) = -9 + 5/6

To subtract these, you need a common denominator. The common denominator is 6, so you need to convert -9 into a fraction with a denominator of 6:

-9 = -54/6

Now, the expression becomes:

-54/6 + 5/6 = (-54 + 5) / 6 = -49/6

So, the result of -12 * 3/4 - 2 * 5/12 is -49/6.
