No, it can be simplified further.
It is: 104/180 = 26/45
65%.
It is: 135/360 = 3/8
Oh, dude, simplifying fractions? That's like trying to simplify my messy love life. So, 360 over 540, you just divide both numbers by their greatest common factor, which is 180. So, 360 divided by 180 is 2, and 540 divided by 180 is 3. Voilà, simplified to 2 over 3. Easy peasy, lemon squeezy!
3/8
It is: 9/5
3/4
1/4
1/3
29/90
180/200 = 18/20 = 9/10
