Let the number be x Twice a number means 2x 7 less than twice a number means 2x-7

n - 7 is equal to or less than 13

12 over 7 as a mixed number = 15/7

9 over 7 in a mixed number = 12/7

Lets say your number us 6 7/12. Make a number line like so |-----------------------------|---------|----------------| 0----------------------------6--------7----------------10 Measure between 6 and 7 and make 12 equal sections out of it. |-|-|-|-|-|-|-|-|-|-|-|-| 6----------------------7 And on the 7th line from 6, it would equal 6 7/12!
