for this question you can say:
21 ÷ 28/15 = 21 × 15/28 
so now you can find the answer:
21×15/28 = 11.25 :)))
i hope this is helpful
have a nice day 
So we are gonna use divide 21÷28 and this will give us 0.75

So divide 0.75÷15 and u get 0.05

so

21÷28 = 0.75

0.75÷15 = 0.05

Answer 0.05 

Hope this helps :)
