Answer 3

Multiply by the reciprocals. Let's start with \[\frac{ \frac{ x+3 }{ 9 } }{ \frac{ x+12 }{ 6 } }\]
How do we proceed?

Answer 4

i think the answer for 1 is c?

Answer 5

\[\frac{ x+3 }{ 9 } * \frac{ 6 }{ x+12 }\]
6 and 9 cross out to become 2 and 3 respectively. How'd you get C?

Answer 6

i got mistaken i dont really understand this

Answer 7

lemme re write that expression\[\frac{ x+3 }{ 3*3 } * \frac{ 3*2 }{ x+12? }\]
do you see how the xs cancel?

Answer 8

and by x I mean 3...

Answer 9

ohh i understadn

Answer 10

so what would the answer be

Answer 11

b?

Answer 12

Yep. I wanna hear some confidence boy.

Answer 13

lol im a girl

Answer 14

for #2 i thinks its either b or d but im not sure

Answer 15

ANYHOW girl. Onwards to #2.\[\frac{ \frac{ 18x-6 }{ 9x^5 } }{ \frac{ 15x+5 }{ 21x^2 } } = \frac{ 18x-6 }{ 9x^2 } * \frac{ 21x^2 }{ 15x+5 }\]
remember that 21 = 3*7
9 = 3*3

Answer 16

WE can factor 6 out of 18x-6 and get 6(3x-1)
same with 15x+5 and get 5(3x+1)

Answer 17

Answer 31

Remember how you add fractions? You can get a common denominator by multiplying them.

Basically I multiplied x+2 and x. Then multiplied each numerator by x+2 and x
