Answer:
D. 6
Step-by-step explanation:
<u>Key skills needed: Set Similarity</u>
1) The easiest way to teach this is by writing out each set, but I will show it to you in 2 ways.
2) The first way is by writing everything out.
Set Q = 4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36
Set Z = 3,6,9,12,15,18,21,24,27,30,33,36
(I only wrote out Set Z to 36 since Set Q ends at 36. Anything greater than 36 won't even be there in Set Q, so no point in writing more.
- The numbers that are common in both sets are --> 6,12,18,24,30,36
- Therefore D would be your answer.
3) The next way is with using a simple pattern.
Set Q contains all even numbers from 4 to 36
Set Z contains all multiples of 3 (no limits)
Therefore, the numbers that are in both sets would be:
The even multiples of 3 that are bigger than 4 and less than 36.
4) Those even multiples of 3 would be ---> 6,12,18,24,30,36
- That means there are 6 numbers in common.
- That means D is your answer.
Both show that D is the answer, so I would say D as the answer very confidently.
