So set up an equation: use x as a variable, the answer. 9/x=42------------- Then, multiply both sides by 1/9 to get x alone.
we got: x=9/42
x=3/14
9/42 = 0.2142857 recurring (that is, 0.2142857142857...)
42/9 = 4.6 recurring (that is, 3.6666...)
42
9.4286
38.1818
0.7778
(42/5)/(35/9)=(42/5)x(9/35)=378/175
1.5556
No - 27 can be divided by 3 & 9. 42 can be divided by 2, 3, 6 & 7
378 divided by 9 = 42
