Answer 1

Ответ:

Пошаговое объяснение:

-4,8+(-2⅔+ (-5\6)) =-4,8 -(-8\3-5\6) = -4 целых 8\10 +( -2*8+(-5*3)\6)=

= -48\10+(-16-15\6)=-48\10- 31\6 = -48*6-31*10\60 = - 288 -310\60= - 598\60=

- 9 целых 58\60 = -9 целых 29\30

Answer 2

Solving the Expression

To solve the expression -4.8 + (-2⅔ + a) when a = -⅚, we can substitute the value of a into the expression and then perform the arithmetic operations.

Substituting the Value of a

Substituting a = -⅚ into the expression, we get: -4.8 + (-2⅔ + (-⅚))

Performing the Arithmetic Operations

First, let's add -2⅔ and -⅚: -2⅔ - ⅚ = -2⅔ - 2⅔ = -5⅓

Now, we can substitute this result back into the original expression: -4.8 + (-5⅓)

Calculating the Final Value

To find the value of the expression, we add -4.8 and -5⅓: -4.8 - 5⅓ = -4.8 - 5.333... = -10.133...

So, the value of the expression -4.8 + (-2⅔ + a) when a = -⅚ is approximately -10.133.
