8.5 is 10% of what number

Question

I don't know what to write here so sorry

Answer 1

Hi Allyson,

 

To solve these problems, remember:

1. "is" means =

2. "of" means multiply

3. percents need to be changed to decimals

 

So . . .

 

  8.5 = .1x       (.1x means ".1 times unknown number")

 

 8.5  =  .1 x   (divide by .1, because division is the opposite of multiplication)

 .1        .1      (.1/.1 = 1, and "1x" is just "x")

 

  85 = x

Answer 2

85. Just think about it this way... 8.5x10 equals 85
