Question

I really need help on my science homewok please x does anyone know what 13% less than 9900 is? thankyou so much :)

Answer 1

Okay so using the formula part/whole = percent/100 youd substitute in your data.

N/ 9900= 13/100

now you would cross multiply this will give you 

100n=128700

now you need to divide by 100 on both sides to find out what your N is. This will tell you what 13% of 9900 is.

N=1287

Now to find out what 13% less than 9900 is you need to subtract your N [1287] from 9900

your answer will be 8,613 :)

Answer 2

Your andwer would be 8613
