Answer:
1) 3
2) 30
Step-by-step explanation:
To find the GCF, you find out the (prime) factors of the two numbers in question. For this question, we would find the (prime) factors that go into 6 and 15.
For the number 6, we can get 2 x <u>3</u> = 6.
For the number 15, we can get <u>3</u> x 5 = 15.
You then underline those factors that you have in common. As you can see, since there is only 1 factor underlined per number, we would have the GCF as 3. On the instance you have more than 1 number underlined, you just multiply them.
Example: 12 and 20
<u>2</u> x <u>2</u> x 3 = 12
<u>2</u> x <u>2</u> x 5 = 20
They both have 2 x 2 in common, so you would get 4 as the GCF.
Moving onto the LCM, I would find this by multiplying each number until i find something similar.
6 x 1 = 6
6 x 2 = 12
6 x 3 = 18
6 x 4 = 24
6 x 5 = <u>30</u>
15 x 1 = 15
15 x 2 = <u>30</u>
The number that is underlined is the lowest common number we have when multiplying and going up by 1, so 30 would be our answer.
A faster way you could've solved this is by knowing that you can't multiply 6 and a whole number to get 15, but you can multiply 6 and a whole number to get 30. This, however, is just prior knowledge.

12^1 = 12
Step-by-step explanation:
Any number raised to the power of one equals the number itself.
Answer:
Missing frequency = 4
Step-by-step explanation:
Given:
Qty Number
1 5
2 6
3 5
4 6
5 □
6 5
7 8
8 4
9 4
10 3
Total 50
Find:
Missing frequency
Computation:
Missing frequency = Total frequency - Counted
Missing frequency = 50 - 46
Missing frequency = 4
1) Average of six people = # of truffles / 6 = 7 ⇒ # of truffles = 6*7 = 42.
2) Average of first four people = # of truffles of the first four / 4 = 8 ⇒ # of truffles of the first four = 4*8 = 36
3) # of truffles of the fourth person = 11
4) # of truffles of the first three people = 36 - 11 = 25
5) # of truffles of the last three people = 42 - 25 = 17
Answer 17.
Given data:
The numbers of books read by Greta are 2.
The expression for the given statement is,
1 month = 2 books
Multiply the above expression by 16 onn both sides.
16(1 month)=16(2 books)
16 months= 32 books
Thus, 32 books read by Greta in 16 months.
