total: 90u
J: 20u
Miche: 800 mL
remainder: 70u - 800 (<= 10/10)
Micha: 21u - 240 (<= 3/10)
left: 49u - 560 (for K)


1/3 of Micha = 200 mL
3/3 of Micha = 600 mL

21u - 240 = 600
1u = 40
90u = 3600


at first 3600 mL

the answer should be 3600ml. Snell can explain how you get the 21 units? (On michael’s portion?) and the 240 comes from where?

ok
after giving Michelle
the remainder is 70u-800

Michael takes 3/10 of remainder
so
3/10 x (70u-800)
= 3/10 x70u - 3/10 x 800
= 21u - 240

let's assume ur ans: 4500mL is correct
& we work forward according to qn to check ans, k?

total is 4500 mL
give Josh: 2/9 x 4500 = 1000 mL
left: 3500mL

give Michelle: 800mL
left: 3500-800 = 2700mL

give Michael: 3/10 x 2700mL = 810mL

but this contradict ur own calculation of Michael getting 600mL


so do u agree that 4500mL is incorrect ans?
