75 students decreased by 80%. Help plz:///

Answers

So,

75 students decreased by 80%. That means that 100 - 80 = 20% remain.

To find 20% of 75 students, just find 10%, which means simply moving the decimal point one place to the left.

75 --> 7.5 = 10% of 75

Therefore,
15 = 20% = 75 because 7.5 * 2 = 15

There are 15 students left.

Hello,
let x the first angle

5x the second
2/3 x the third

x+5x+2/3x=180
==>20x/3=180
==>x=27 (°)
5x=5*27=135
2/3*x=2/3*27=18

27+135+18=180
