30 boys

because if  14 girls    = 28 girls
                 15 boys   =  n  boys
 14n= 28*15
 14n= 420
     n= 420/14
     n= 30

Ratio!!!

You can just simply divide 28 to 14 then multiply the result to get how many boys there are in 28 girls :)

28/14 = 2

then

15 * 2 = 30

therefore there are 30 boys :)
