I want to ask Maths

She drinks =(1.5*(1/3)-0.25)(2/5)
=0.04L

Sorry it should be 0.1L(100mL)

As Cindy drinks 2/5 of the remaining soft drink=1.5/3-0.25=0.25L

0.25 is the volume of remaining soft drink after Betty drank 0.25L

Correction: She drinks =(1.5*(1-1/3)-0.25)(2/5)=0.3L I forgot to type 1-

Be careful of the question: How much does Cindy drink not the remaining volume!!!We are all wrong at first!

1.5飲左1/3，即係仲有1L
跟住又飲左0.25，即係仲有0.75L
之後又飲左2/5，即係仲有0.45L~

1.5x(1-1/3)-0.25)x(1-2/5)因為係飲左之前剩番果d，所以會係1-
