The order of operations is a rule that tells you the right order in which to solve different parts of a math problem. The order of operations is important because it guarantees that people can all read and solve a problem in the same way.
Part 1: should be C. Because the question said 1.2 added to a number.
Part 2:16.8
The answer is b because all of the other numbers in the parentheses are less then one so there can’t be a growth if the number is less than one
They need to be like terms (so change the denominators into things that match)
<u>1 </u>x3 = <u>3</u>
4 x3 = 12
<u>1 </u>x4 = <u>4</u>
3 x4 = 12
4/12 + 3/12 = 7/12
So, 7/12 of the money was spent.
