Answer 1

г) = 1,3 - 4,44/3,7 = 1,3 - 1,2 = 0,1

д) может быть нужно перевести в нормальную дробь из десятичной

е) =8,364/ 4,08 -0,82 = 2,05 - 0,82 =1,23

Answer 2

г)0,6

д)929,8 ??????

е)1,23

Answer 3

г) 10,79/8,3-(5-0,56)/3,7 =

To solve this expression, we need to follow the order of operations, which is PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Here, there are no parentheses or exponents, so we can move straight to multiplication and division, then addition and subtraction.

10,79 divided by 8,3 is 1.299 and (5-0,56) divided by 3,7 is 1,236.

So, the expression becomes:

1,299 - 1,236 = 0.063

Therefore, 10,79/8,3-(5-0,56)/3,7 = 0.063.

д) 46,08/(1,5/1,116)*0,04+44,8 =

Again, we need to follow the order of operations, which means we need to start with the division inside the parentheses.

1,5 divided by 1,116 is approximately 1.344.

So, the expression becomes:

46,08/1.344*0.04+44.8 =

Next, we can perform the multiplication and division:

46,08 divided by 1.344 is approximately 34.322, and 34.322 multiplied by 0.04 is 1.373.

So, the expression becomes:

1.373 + 44.8 =

Finally, we can perform the addition:

1.373 + 44.8 = 46.173.

Therefore, 46,08/(1,5/1,116)*0,04+44,8 = 46.173.

е) 8,364/(8-3,92)-2,05*0,4=

Following the order of operations, we need to start with the parentheses:

8 - 3.92 is 4.08.

So, the expression becomes:

8,364/4.08 - 2.05*0.4 =

Next, we can perform the division:

8.364 divided by 4.08 is approximately 2.051.

So, the expression becomes:

2.051 - 2.05*0.4 =

Finally, we can perform the multiplication:

2.05 multiplied by 0.4 is 0.82.

So, the expression becomes:

2.051 - 0.82 =

And performing the subtraction:

2.051 - 0.82 = 1.231.

Therefore, 8,364/(8-3,92)-2,05*0,4 = 1.231.
