Пошаговое объяснение:

$(-0,76-0,44):2\frac{2}{3}=-1,2:2\frac{2}{3}=-1\frac{2}{10}:\frac{8}{3}=-\frac{12}{10}*\frac{3}{8}=-\frac{9}{20}=-0,45$

Answer 2

To solve the expression (-0.76 - 0.44) ÷ 2 2/3, we need to convert the mixed number 2 2/3 into an improper fraction.

To do that, we multiply the whole number (2) by the denominator of the fraction (3), then add the numerator (2) to get the new numerator. So, 2 2/3 can be written as (2 × 3 + 2)/3 = 8/3.

Now we can substitute this value back into the expression:

(-0.76 - 0.44) ÷ 8/3

To divide by a fraction, we multiply by its reciprocal:

(-0.76 - 0.44) × 3/8

Now we can perform the subtraction and multiplication:

= (-1.20) × 3/8 = -3.60/8 = -0.45

Therefore, (-0.76 - 0.44) ÷ 2 2/3 is equal to -0.45.
