how did u get that answer? just asking because i want to be able to figure it out on my own

4. anonymous

40 / .8 = 50 the slash equals division. 50 * .8 = 40

5. lalaly

let the number be x$\frac{80}{100} \times x=40$solve for x

yeahh i'm right .8 x = 40 x = 40 * (5/4) = 10 * 5 = 50 80% of 50 (answer) is 40

Yes that is how you convert a percent to a decimal :)
