Finding the volume for what?
Answer:
first evening = 21 phone calls
second evening = 11 phone calls
third evening = 84 phone calls
Step-by-step explanation:
Total phone calls = 116
Let
Number of calls in the first evening = x
The second evening = x - 10
The third evening = 4x
Total phone calls = first evening + second evening + third evening
116 = x + (x - 10) + 4x
116 = x + x - 10 + 4x
116 + 10 = 6x
126 = 6x
x = 126 / 6
x = 21 phone calls
Number of calls in the first evening = x
= 21 phone calls
The second evening = x - 10
= 21 - 10
= 11 phone calls
The third evening = 4x
= 4(21)
= 84 phone calls
Khan academy has a lot on this sorry I couldn't answer bro

I believe the correct answers are 534 over 999 and 178 over 333.
Because a fraction is basically division, when you divide 534 by 999 you get 0.534. The same thing goes for when you divide 178 by 333.
534/999=0.534
178/333=0.534
