1) n:9=52:63
n/9 = 52/63
n = (9)(52)/(63) = 52/7
2) 4:7=6:n
4/7 = 6/n
(4)n = (6)(7)
n = 42/4 = 21/2 = 10.5

1) n=52/63 * 9
2) 4*n=6*7 => n= 6*7/4

i've put the instructions in parentheses...
1. n:9 = 52:63 (cross multiply)
63n = 52 x 9 (divide both sides by 63 to get "n" by itself)
n = (52 x 9)/63 (multiply and divide)
n = 7.43 (this is the answer)
Therefore, "n" is equal to 7.43.
2. 4:7 = 6:n (cross multiply)
4n = 7 x 6 (divide both sides by 4 to get "n" by itself)
n = (7 x 6)/4 (multiply and divide)
n = 10.5 (this is the answer)
Therefore, "n" is equal to 10.5.
I hope this helps!

Solve as a proportional problem
n : 9 = 52 : 63
The means are 9(52)
The extremes are 63n
63n = 9(52)
63n = 468
63n / 63 = 468 / 63
n = 468 / 63
n = 7.428571429
