I cant find the answer.

The numerator is 3, so the whole thing would say 3/11=12/44

Step-by-step explanation:

divide the second fraction down as much as possible, and you will get 3/11.

12 divided by 4 equals 3

44 divided by 4 equals 11

so 3 is the numerator and 11 is the denominator

3

Step-by-step explanation:

lets make teh blank x

x/11 = 12/44

x/11 = 3/11

x = 3

or

x/11 = 12/44

4x/11 = 12/44

4x = 12

x = 3

i used the pitagoras theoreme

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

you,

mrb

(a + b) (a^2 - a b + b^2)
