So if you put the into fractions it would mean that 6/7 = n/4.2. Then, you would cross multiply in order to get 6(4.2) = 7n. Next, you would simply and get that 25.2 = 7n. To get n by itself, you would then divide each side by 7. When dividing 25.2 by 7, you would get 3.6. 7n divided by 7 is equivalent to n. Therefore; n = 3.6.
