Answers & Comments
Answer:
LETTER A: 3 is not a factor of 20
LETTER B: 3,6,7 and 8 are not factors of 20
LETTER C: all if the numbers are multiples of 5 but 15 is not a factor of 20
LETTER D: all numbers are multiples of 5 & 10 but 30, 40 and 50 are not factors of 20.
Therefore, there is no correct option among the choices given.
The factors of 20 are: 1,2,4,5, 10 and 20
Step-by-step explanation:
Answer:
1. A - All of of them are factors of 20
2. C - 84 cannot be divided by 5
3. C - When you multiply 7 by 7, the answer will be 49
4. B - 15 is a composite number
5. C - 2 is the first prime number
6. D - 2x3x3x3 is equals to 54
7. A - 1, 2, 4, and 8 are the common in the numbers
8. C - 10 is the greatest possible number that can be divided by both 30 and 40
9. D - 8 is the GCF of 32 and 40
10. D - 12 and 24 are the only numbers in common
11. C - 120 is the LCM of 6, 8, and 10.
12-17. Where's the story problem po? I can't see it.
18. There is no choices included po.
19. 27/5 is the improper fraction of 5 2/5 but why it is not included in the choices po? Or maybe letter D is a typo error?
20. B - 1/2 is the lowest term of 30/60. Just divide them by 2.
Hope it helps :)
