Hey!

------------------------------------------------

~Turn into decimal

40% = 0.4

~Multiply

200 * 0.4 = 80 (7th graders in the band)

Now, we can write this as 80 is 20% of what number.

~Turn into decimal

20% = 0.2

~Divide

80 / 0.2 = 400

------------------------------------------------

Hence, there are \Large\boxed{\mathsf{400}} students in band!

------------------------------------------------

Hope This Helped! Good Luck!

I have $100. I spent $40 on a prize and $45 on food. How do I figure out what % is purchase is from the original amount I had?
Paladinen [302]
You could say that you spent (purchased) 85% of the money that you had.

You spent a total of $85.

If you create the fraction 85/100, that is the same as saying you spent 85% of the money.
