Answer:
2.2
Step-by-step explanation:
Order of operations states that you begin with what is in the parentheses followed by exponents, multiplication/division, then addition/subtraction from left to right. 9 times 0.3 is 2.7. 2.7 - 0.5 = 2.2.
(9 x 0.3) -0.5
do the multiplication that's in the ( ) first
2.7-0.5= 2.2
