14/18 = 7/9
18/100=0.18=9/50=18%
1/9
9/18 simplifies to 1/2 or 0.5
9/18 = 1/2 after dividing the numerator and denominator by 9.
9x + 9 - 1 = 9x + 8
Percent means "out of 100", therefore 18% is 18/100. You can simplify this to 9/50.
7/18 - 5/18 = 2/18 = 1/9
First you have to know that dividing by 9/18 is the same as multiplying by 18/9.So you have (1/3)/(9/18) = (1/3)*(18/9) = 18/(3*9)you can simplify by 9= (2*9)/(3*9)=2/3
6c-18=4c Why can rearrange this and simplify to 2c=18, which means that c = 9
You have to get the same common denominator, 9x2 is 18, so 7x2 is 14. 14/18-5/18 is 9/18. 9/9 is 1 and 18/9 is 2, so you are left with 1/2
180/580 = 18/58 = 9/29
