Question

Вычислить (8 7/12 - 2 17/36) * 2,7 - 4 1/3 : 0,65 = помогите пожалуйста

Answer 1

=(8*12+7)/12 - (2*36+17)* 2 7/10 - 4=
=(103/12 - 89/36) * 27/10 -4=
= (3*103/3*12 - 89/36)* 27/10-4=
=(309-89)/36*27/10-4=
=220/36*27/10-4=
=5940/360-4=
=(5940-4*360)/360=
=4500/360=12,5

1 3/10:65/100=
= 13/10:65/100=
= (13*100)/(10*65)=
=1300/650=2

Answer 2

Calculation

To compute the expression *(8 + 7/12 - 2 + 17/36) * 2.7 - 4 1/3 ÷ 0.65*, we can follow the order of operations: parentheses, multiplication and division (from left to right), and addition and subtraction (from left to right).

First, let's simplify the expression inside the parentheses: *(8 + 7/12 - 2 + 17/36) = (8 + 0.5833 - 2 + 0.4722) = 6.0555*

Now, the expression becomes: *6.0555 * 2.7 - 4 1/3 ÷ 0.65*

Next, we can calculate the result of the division: *4 1/3 ÷ 0.65 = 13/3 ÷ 0.65 = 4.9231*

Now, the expression becomes: *6.0555 * 2.7 - 4.9231*

Finally, we can calculate the result of the multiplication and subtraction: *6.0555 * 2.7 - 4.9231 = 16.3669 - 4.9231 = 11.4438*

So, the result of the expression *(8 + 7/12 - 2 + 17/36) * 2.7 - 4 1/3 ÷ 0.65* is 11.4438.
