Answer 1

12цел.²\15-(7цел¹¹\15+2цел8\15)= 12цел.²\15-10цел.⁴\15=11цел.17\15-10цел.⁴\15=1цел.¹³\15

Answer 2

To simplify the given expression, let's start by working with the whole numbers separately from the fractions. Then, we'll add or subtract the fractions accordingly.

Expression: 12 целых 2/15 - (7 целых 11/15 + 2 целых 8/15)

Step 1: Handle whole numbers 12 - (7 + 2)

Step 2: Handle fractions 2/15 - (11/15 + 8/15)

Now, we need to combine the fractions inside the parentheses: 2/15 - (11/15 + 8/15) = 2/15 - 19/15

Next, we need to find a common denominator to combine the fractions: The common denominator for 15 and 1 is 15.

2/15 - 19/15 = (2 - 19) / 15 = -17 / 15

Finally, combine the whole numbers with the simplified fraction: 12 - (7 + 2) - 17/15

Now, finish the operations inside the parentheses: 12 - 9 - 17/15

Perform the subtraction: 3 - 17/15

To represent this as a mixed number, we need to convert the improper fraction to a mixed number: 3 - 17/15 = 2 + (15 - 17)/15 = 2 - 2/15

So, the final result of the expression is: 2 целых 2/15
