cross multiply:
5 x 42 = 210
6 x N = 6N
equate:
6N=210
solve for N:
N= 210/6 =35

Problem: 5/6 = N/42
Working:
Isolate the unknown in the fraction. Bring the denomination from right to left side.
When the denom crosses the equal sign it becomes part of the numerator and vice versa so..
5/6*42/1 = N
(5*42)/(6*1)=N
210/6=N
35=N
Thus: 5/6=35/42

Proportion
Multiply the means
Multiply the extremes
5/6 = N/42
Means = 6N
Extremes = 5(42)
5/6 = N6
6N = 5(42)
6N = 210
6N/6 = 210/6
N = 35
The answer is N = 35
Insert the N value into the equation

5/6 = N/42
easy way... notice 6*7 = 42, so (5*7) / (6*7) = N/42 and N=35.
Harder way 5/6 = N/42 Multiply both sides by 42
42 * 5/6 = N. Plug into calculator and get 35 :)

solve for N:
5/6=N/42
5*42=N*6
210=6N
35=N
so 5/6=35/42
