Answer 3

To solve the expression, let's break it down step by step:

First, let's simplify the expression within the parentheses:

5 цел 17/19 = (5 * 19 + 17) / 19 = (95 + 17) / 19 = 112 / 19 4 цел 14/19 = (4 * 19 + 14) / 19 = (76 + 14) / 19 = 90 / 19

Now, substitute these simplified values back into the original expression:

12 цел 2/19 - (112/19 + 90/19)

Next, add the fractions within the parentheses:

112/19 + 90/19 = (112 + 90) / 19 = 202 / 19

Now substitute this value back into the expression:

12 цел 2/19 - (202/19)

To subtract the fraction within the parentheses, we need a common denominator:

12 цел 2/19 - (202/19) = (12 * 19 + 2) / 19 - (202/19) = (228 + 2) / 19 - (202/19) = 230/19 - (202/19)

Subtract the fractions:

230/19 - 202/19 = (230 - 202) / 19 = 28/19

Therefore, the simplified form of the expression 12 цел 2/19 - (5 цел 17/19 + 4 цел 14/19) is 28/19.
