To get the answer we can use proportion 86 --------------45% x ---------------- 100% Now cross multiply x*45%=86*100 45x=8600 /:45 (divide both sides by 45) x=191.11 - its the answer
The best thing to do is to find 1%, and you can do this by diving 86 by 45. 86/45= 1.9111, and you've then got to multiply this by 100, and this gives you 191.11
Hope this helps :)
