i just need to know what this is.. i have a few more ... what is 13.75% of 38, what percent of 8 is 5 and finally what percent of 80 is 7

7% of 3/4 = 7 *3/ 4 *100 = 0.0525

13.75% of 38  = 13.75 *38/ 100= 5.225

 suppose % is x

 x *8/100 = 5

x = 5*100/8

  62.5 

x = 62.5 %

hence the 62.5 % of 8 will be  5

 again  let % x 

so x *80/100 = 7

    x =700/80 = 8.75 

therefore 8.75% of 80 will be 7

Regarding any clarification plz let me know.

I will be happy to help you.
