Wow, fairly simple although it seems hard. :D

ou need to get it over 100 for easy change to a decimal. 

7/20 is equal to 35/100. 

You multiplied the 20 by 5 to get 100 
You need to multiply the 7 by 5 to get 35 

You get 35/100 

Any number over 1 is itself. 

Divide 100 by 100 to get 1 

Divide 35 by 100 (You can do that right) to get 0.35 

=0.35
