3/5 of a number is 30. What's the number?
777dan777 [17]

To figure out the number we need to set up our equation to make more sense.

<u>3/5 = 30/x</u>      (x is our missing number)

We know that what ever you do to the top of the fraction you can do to the bottom.

So if we multiply 3 x 10 we get 30.

Therefore to get the number we must multiply 5 by 10

5 x 10 = 50

So our answer and missing number is 50
