septiembre 15 thats how you spell it
You write it as 3/15. However, that can be simplified to 1/5.
tresTres other wise just write it 3
It is: 15 and 3/10
3 * 15 = 45 or 15 = 45 / 3 or 3 = 45 / 15
3/20 = .15 = 15% Or 3/20 = 15/100 = 15%
The factors of 15 are 1, 3, 5 and 15.
Write "9" then the forward slash "/" and then "15". Or you can write the 9 above a horizontal line with the 15 below that line.
15/100 or 3/20
1/5
