÷

First, apply the rule: a ÷

= a ×


×
Second, apply the rule:

×

=

Third, multiply 4 × 3 to get 12, and 9 × 2 to get 18.
Fourth, find the GCF of 12 and 18.
Factors of 12: 1, 2, 3, 4, 6, 12
Factors of 18: 1, 2, 3, 6, 9, 18
The GCF is 6.
Fifth, divide the numerator by the GCF.

÷ 6 = 2
Sixth, divide the denominator by the GCF.
18 ÷ 6 = 3
Seventh, rewrite your fraction.

Answer as fraction:

Answer as decimal: 0.6667
The range of this data set is 142.
so hmmm on average on the last 7 test, you get 82, so hmmm we could say that on each of the 7 tests you got 82, so you got 82, 7 times.
now, let's say in the 8th test, you get a grade of "g", now, if we were to get an average of all 8 tests, that means the average will simply be (82*7) + "g", and we know that's 84, so
