    OKAY but what does B equal? I have to graph it. Needs to be a number ?? Maybe I don't get what you did.

    I have to do ten of these and sorry but I'm OLD and didn't quite follow HOW you got the answer and no I didn't see it sorry. I sort of see the steps of how to solve it.

    40%=.4 .4=2/B multiply both sides by B .4B=2 divide both sides by .4 B=2/.4 B=2 divided by .4 B=2 divided by 4/10 B=2 divided by 2/5 =2*5/2=5 because the twos cancel

    40%=.4=4/10=2/5 maybe this is easier for you to understand so 2/5=2/B how can these fractions be equal what does B have to be in order for the equation to be true
