for which value of n will the function 4/9 and n/27 be equivalent?

4/9=n/27
9n=27*4
n=12 ? check that. 
am i suppose too divided 9 when i multiply 27 with 4 ?

Yes. After you multiply 27 * 4, divide the product by 9 to get the value of n.

thanks i qot n= 12

Right.

Or you can see the denominator (bottom number) is multiplied by 3 to get from 9 to 27 so you multiply the numerator top number by 3. 4 x 3 = 12

i think she needs to apply this rulz that says : a/b=c/d so ad=bc
