What is 34% of 60000000
Ainat [17]

(Lets hope i'm right :p)


The first thing you do is make "34%" into a fraction. That would be 1/34.

After, you would multiply.


1/4 x 60000000/1 = ?

(Use cross multiply if you know)

60000000 divided by 4 = 15000000

1/1 x 15000000/1 = 15000000/1 OR 15000000


Answer: 15000000/1 or 15000000
