A + s = 279
s = 2a
a + 2a = 279
3a = 279
a = 279/3
a = 93 <=== adult
s = 2a
s = 2(93)
s = 186 ....students
Answer:
8%
Step-by-step explanation:
70.20−65.00=5.20
(5.20/65.00)×100=8
7/8 can be converted to .875 because 1/8 is .125 and .125*7=.875. Add -12 to it so the answer is -12.875
1/3 is greater because it is equal to 0.33333......
1/8 is equal to 0.125. :D
