Answer 1

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!
