Use the percent equation to answer the following.

solve the percent equation for b.
percent equation is a= p% . b

i saw in text it set up as cross products a/b = p/100.

I thought about putting formula b=p/a for answer or b = 100 using 1 for a, p

• algebra -

a = P% b.
Change % to decimal:
a = (P%/100%) * b,
a = (P/100)b,
Multiply both sides by 100/P:
b = 100a/P.

thank you so much Henry, i really appreciate your help.
