Answer 1

Ответ:

Пошаговое объяснение:

-1,53 : 0,5 (-4 1/18 - 1 1/5 + 3 1/5)

-153/100 : 1/2 * (73/18-6/5+16/5)

-153/100 : 1/2 * (- 37 / 18)
17/50 * 37/2

629/100

Answer 2

Let's break down the expression step by step:

-4 1/18 can be written as -4 + 1/18 -1 1/5 can be written as -1 + 1/5 3 1/5 can be written as 3 + 1/5

Now let's substitute these values into the expression:

-1,53 : 0,5 (-4 1/18 - 1 1/5 + 3 1/5)

= -1,53 : 0,5 [(-4 + 1/18) - (-1 + 1/5) + (3 + 1/5)]

= -1,53 : 0,5 [(-4 + 1/18) + (1 - 1/5) + (3 + 1/5)]

= -1,53 : 0,5 [(-4 + 1/18 + 1 - 1/5 + 3 + 1/5)]

= -1,53 : 0,5 [-4 + 1/18 + 1 - 1/5 + 3 + 1/5]

Now, let's calculate the values inside the square brackets:

-4 + 1/18 + 1 - 1/5 + 3 + 1/5 = -4 + 1/18 + 1 - 1/5 + 3 + 1/5

= -4 + 1 + 1/18 - 1/5 + 3 + 1/5

= -4 + 1 + 3 + 1/18 - 1/5 + 1/5

= -4 + 1 + 3 + 1/18 + 1/5

= -4 + 1 + 3 + (5 + 18)/(18*5)

= -4 + 1 + 3 + 23/90

= 0 + 3 + 23/90

= 3 + 23/90

Now, let's calculate the division:

-1,53 : 0,5

= -1,53 / 0,5

= -1,53 * (1/0,5)

= -1,53 * 2

= -3,06

Finally, substitute the result of the division (-3.06) into the expression:

-1,53 : 0,5 [3 + 23/90]

= -3,06 [3 + 23/90]

= -3,06 * 3 + (-3,06 * 23/90)

= -9,18 + (-0,79333...)

= -9,18 - 0,79333...

= -9,97333...

Therefore, the value of the expression is approximately -9.97333...
