Answer 1

Hi Jasmine,

 

 

  how do i change numbers to percents for say 12 is what percent of 20?  

 

Since percent is out of 100, make two ratios and then cross multiply

 

Part over whole is equal to part over whole.

 

12  =   x

---     ----

20      100

 

12(100)=20x

 

1200=20x

 

60=x

 

 

ANSWER:  60%

 

Hope this helps you understand the process.
