Answer:
3/8 cup of butter
Step-by-step explanation:
1/4 / 2 = 1/8
1/8x3=3/8

18 & 18. I like it.
The square root of a natural number won't be rational unless the number is a perfect square. So not a and not b but yes to C.
For d, -0.125374..., we can't really tell. The three dots tells us it goes on. There's no indication of a repeat but we can't assume it doesn't repeat either. For d the correct answer is cannot be determined.
OK, onto 18.
The square root of 12 is irrational so has a nonterminating, nonrepeating decimal expansion.
7/8 has a finite decimal expansion, 0.875. When the reduced denominator doesn't have any prime factors besides 2 and 5 we'll get a finite decimal expansion. Answer: b
5/11 has 11 as a factor in the denominator, so is an infinite repeating decimal.
I'll guess there's three dots after 0.81818181 so that one doesn't terminate either.

Bonus
0.21 rational, equal to 21/100
3/12 rational, it's the ratio of integers
√12 - 2 is irrational because of the √12
4.125... can't really tell because the ... may hide a repeating or nonrepeating part.
Answer:
First Game: 65 points
Second Game : 65 points
Third Game : 59 points
Step-by-step explanation:
Average = sum of values/number of values
The number of values = 3, an d average = 63
63 = x/3
63 * 3 = x
189 = x
Now 189 is the sum of points over two games.
Their first two games are worth the same, so lets call that s +s = 2s
Their 3rd game is worth 6 less points than s, so s-6
let's add up all the terms:
2s + (s - 6) = 3s - 6
Solve:
3s - 6 = 189
3s = 195
s = 65
The first two games are worth 65, and the third game is worth 65 - 6 = 59.
