90 - 38 = 52 degrees.
Since 38+90=128 128+38 = 166 So there is 166 students
Approximately 90%
It is 0.9/0.38 = 90/38 which can be simplified, if you so wish.

38% of 90 = 0.38 x 90 = 34.2
It is: (90+38)/2 = 64
90-
One atom of Strontium-90 contains 38 electrons.
90 - 38 = 52 degrees.

All molecules of Strontium have the same number of protons, 38.
The only common factors of 38 and 90 are 1 and 2, so it is not possible for a common factor of 38 and 90 to be greater than 2, much less 20.
Since 38+90=128 128+38 = 166 So there is 166 students
Approximately 90%
It is 0.9/0.38 = 90/38 which can be simplified, if you so wish.
