Final answer:
To find the result of each expression, we need to follow the order of operations. For expressions a, b, c, and e, we simplify the expression step by step using multiplication, division, addition, and subtraction. For expression g, we simply divide 18 by 1.
Step-by-step explanation:
To find the result of each expression, we need to follow the order of operations, which is parentheses, exponents, multiplication/division (from left to right), and addition/subtraction (from left to right). Let's go through each expression:
a. 27 + 8 / 5 - 7 = 27 + (8 / 5) - 7 = 27 + 1.6 - 7 = 20.6 - 7 = 13.6
b. 27.0 + 8.0 / 5.0 - 7.0 = 27.0 + (8.0 / 5.0) - 7.0 = 27.0 + 1.6 - 7.0 = 20.6 - 7.0 = 13.6
c. 25 % 7 + 9.0 = 25 % 7 + 9.0 = 4 + 9.0 = 13.0
e. int(15.0 + 12.0 * 2.2 - 3 * 7) = int(15.0 + (12.0 * 2.2) - (3 * 7)) = int(15.0 + 26.4 - 21) = int(40.4 - 21) = int(19.4) = 19
g. 18 / 1.0 = 18 / 1.0 = 18
