n is equal to 2.5
I divided 20 by 5 to get 4. = 20 ÷ 5 = 4. So, I divide 10 by 4 to get n. = 10 ÷ 4 = 2.5
Or we can do this solution.
20 5
---- = ---- ; do cross multiplication. 20n = 10(5)
10 n
20n = 50 ; to get n, divide both sides by 20. 20n / 20 = 50 / 20 = n = 2.50
Whichever way: 20/10 = 5/2.5
