Answer 4

What is the largest factor 6 and 4 share in common?

Answer 5

yes

Answer 6

what is the GCF of 6 and 4?

Answer 7

6:1,2,4
4:1,2,3,6
so the answer is 2

Answer 8

you got it, so the ratio of 6 to 4 can be reduced to the ratio of 3 to 2

How did I get 3 to 2? I divided 6 by 2 to get 3 (the first part of the ratio) then I divided the second part 4 by 2 to get 2

So

6:4 turns into 3:2

after dividing both parts (6 and 4) by the GCF 2

Answer 22

the answer right?

Answer 23

we'll see, what do you get

Answer 24

i got 5 to 3

Answer 25

so the answer is 5:3

Answer 26

now ask yourself: do the numbers 5 and 3 have any factors in common (other than 1)?

what do i have to do

Answer 36

if you have something like

2 * ( 1 + 7)

you can multiply that outer "2" by each term inside the parenthesis like this

2 * 1 + 2 * 7

Answer 37

Or you can go backwards, and start with something like

8 * 3 + 8 * 9

and turn it into

8 * (3 + 9)

Answer 38

oh okay
