Question

Вычислить: 2 6/30+(-9 12/30)+2 10/30 = ?

Answer 1

2, 6/30-9, 12/30+2, 10/30= 4, 16/30- 9, 12/30= -4, 13/15

Answer 2

2 + 6/30 + (-9 + 12/30) + 2 + 10/30

First, let's simplify the fractions: 6/30 = 1/5 12/30 = 2/5 10/30 = 1/3

Now we can substitute the simplified fractions back into the equation: 2 + 1/5 + (-9 + 2/5) + 2 + 1/3

Next, let's simplify the equation by combining like terms: 2 + 1/5 - 9 + 2/5 + 2 + 1/3 = (2 - 9 + 2) + (1/5 + 2/5 + 1/3) = -5 + 5/5 + 3/15 = -5 + 1 + 1/5 = -4 + 1/5

So the final answer is: -4 + 1/5
