Complete the sentence.<br><br><br> 7 is 35% of _________.
Sonbull [250]
<span>Okay, pretend the number equals X,
so x is 35%, and that would equal 7, so then 
x is still 35/100 = 7 
x = 7 which is 100/35 
x = 700/35 
x = 20 
then you get the number = 20 
I hope this was helpful, and good luck! :P</span>
