Question

(4 1/2-0,7)*(1,85+3,20)

Answer 1

(4 1/2-0,7)*(1,85+3,20)= 3,8*5,05=19,19

Answer 2

1) 4 1/2-0,7=4,5-0,7=3,8;
2) 1,85+3,20=5,05;
3) 3,8*5,05=19,19

Answer 3

To solve the expression, we'll follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction.

First, let's simplify the expression within the parentheses:

(4 1/2 - 0.7) * (1.85 + 3.20)

To simplify the first set of parentheses, convert the mixed number 4 1/2 to an improper fraction:

4 1/2 = 9/2

Now we can simplify:

(9/2 - 0.7) * (1.85 + 3.20)

Next, subtract 0.7 from 9/2:

(9/2 - 0.7) = 4.5 - 0.7 = 3.8

Now we have:

(3.8) * (1.85 + 3.20)

Next, simplify the second set of parentheses:

(3.8) * (1.85 + 3.20) = (3.8) * (5.05)

Finally, multiply the two numbers:

(3.8) * (5.05) = 19.19

Therefore, the result of the expression (4 1/2 - 0.7) * (1.85 + 3.20) is 19.19.
