Step-by-step explanation:
there are
150 + 83 + 57 + 10 = 300 students in total.
so,
100% = 300
1% = 100%/100 = 300/100 = 3
a.
150 / 3 = 50%
b.
83 / 3 = 27 2/3 % or 27.66666...%
c.
57 / 3 = 19%
d.
10 / 3 = 3 1/3 % or 3.333333...%
2+3 is 5. + 4 is 9. -5 is 4. -2 is 2. -3 is negative 1. 4 times 6 is 24. - 1 is equal to 23
so 23
