This is what i tried

6250:275=22.8 (1 d.p)

Answer 1

She can serve up to 22 people

Explanation:

Given that the total amount of soup that Joy makes in liters is 6.5L

also that the portions are in ml

280ml to liters we have 280/1000= 0.28L

our aim is to know weather 6.5L divided by 0.28L can be up to 22

let us try it out

6.5/0.28= 23.214

we have 23.

Therefore the 6.5L can serve up to 22 portions of 280ml in 6.5 L of soup
