The ratio 20/10=5/n. What does n equal?
DIA [1.3K]
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
