Answer 2

To simplify the expression:

(1,24-1 1/25)*2,5-1/6:1/3

First, let's convert the mixed numbers to improper fractions:

1 1/25 = (25/25) + (1/25) = 26/25

Now the expression becomes:

(1 24/25 - 26/25) * 2.5 - 1/6 ÷ 1/3

Next, let's work on the subtraction inside the parentheses:

(24/25 - 26/25) * 2.5 - 1/6 ÷ 1/3

Now, subtract the fractions inside the parentheses:

(-2/25) * 2.5 - 1/6 ÷ 1/3

Multiply -2/25 by 2.5:

(-2/25) * 2.5 = -5/5 * 2/25 = -10/25 = -2/5

Now the expression becomes:

(-2/5) - 1/6 ÷ 1/3

Now, let's deal with the division:

(-2/5) - (1/6 ÷ 1/3)

To divide by a fraction, you can multiply by its reciprocal:

(-2/5) - (1/6 * 3/1)

Now, multiply the fractions:

(-2/5) - (3/6)

Both fractions have the same denominator, so you can subtract them directly:

(-2/5) - (3/6) = (-2/5) - (1/2)

To subtract these fractions, they need a common denominator, which is 10:

(-4/10) - (5/10)

Now, subtract the fractions:

(-4/10) - (5/10) = (-4 - 5) / 10 = -9/10

So, the simplified value of the expression is -9/10.
