Write this ratio as a fraction in simplest form without any units. 1 hour to 48 minutes

EDIT : On further thought, I had it all wrong, and completely messed up. Props to @Lindseysalter84, who's answer is beneath mine's, for making me realize.

An hour is made up of 60 minutes. That would make the ratio 60 : 48 minutes. So now we would have to simplify. I take it real slow.

60 ÷ 2 = 30
48 ÷ 2 = 24

You can keep on simplifying.

30 ÷ 2 = 15
24 ÷ 2 = 12

It can still be simplified.

15 ÷ 3 = 5
12 ÷ 3 = 4

And so there's your answer in simplified form. is the answer in simplified form, otherwise known as 1.
