b)about how much orange juice and pop do you need to serve 15 people? 20 people?
plz say how you answered this
O : P => 2 : 5
(a) 1 liter of pop to serve 7 people
=> 5 units = 1
1 unit = 1 / 5
Orange juice => 2 units
Hence, Orange juice needed is 2 * 1 / 5 = 0.4 liters
(b) If 1 liter of pop is needed to serve 7 people, then we will need (1 / 7) * 15 for 15 people
i.e. 2.14 liters
As the ratio of O : P = 2 : 5,
5 units = 2.14
1 units = 2.14 / 5
For Orange juice, we will need 2 * 2.14 / 5 = 0.856 liters for 15 people
368 estimated to the nearest Hundredth is 400, and 231 is 200
also to the fiftieth, 350 and 250
There are a total of 900 /999-99/ 3-digit numbers. And they are 900 consecutive numbers, 1/6th of these should be divisible by 6, 900/6=150 numbers. So the answer to your question is answer is... 150! :3
Hope I helped.
