Pairs of numbers between 1 and 6 that add up to 7: 1+6, 2+5, 3+4, 4+3, 5+2, 6+1
Pairs of numbers between 1 and 6 that add up to 8: 2+6, 3+5, 4+4, 5+3, 6+2
Pairs of numbers between 1 and 6 that add up to 9: 3+6, 4+5, 5+4, 6+3
6 for 7, 5 for 8, 4 for 9. 15 in all
To simplify the ratio. You have to find both of these numbers Greatest common factor. Which happens to be 3 :P
So divide each number by 3
15 ÷ 3 = 5
---------------
3 ÷ 3 = 1
So this means our new simplified ratio is...
5 seconds to 1 minute.
Good Luck! :)
