B) because if you round your numbers, -18 1/4 is -18 and 2 2/3 rounds up to positive 3
Answer: 3 × 10^4
Step-by-step explanation:
9x10^2 is how many times as much as 3x10^-2?
9 × 10^2 = 9 × 100 = 900
3 × 10^-2 = 3 × 0.01 = 0.03
We then divide, this will be:
= 900/0.03
= 30000
This can be represented as:
30000 = 3 × 10^4

Step-by-step explanation:
The phrase is “ n students
into groups of 6”
Think about what makes sense.
Separating n students into 6 equal
groups means dividing n students into
6 equal groups. So, write a division
expression.
& separated \ \underline{n \ students} \
Division is not commutative. The order
in which we divide numbers matters.
So, while n \div 6 represents the
number of students in each group,
n \div 6 does not.
The answer is n \div 6 .
