One,

42/3 * 2 = 28m

The rest of the next day

28/( 1- 1/7) = 98/3m

The rest of the first day

98/3/( 1-2/9) = 5 1m

Second,

16/( 1- 1/3) = 24

The rest of the next day.

(24+6)/( 1- 1/4) = 40

The rest of the first day.

(40+20)/( 1- 1/5) = 75

Original.

Third,

(5+1/2)/(1/2) =11kg

What's left after giving C.

1 1/( 1/2)= 22k g。

What's left after giving B.

(22+1/2)/(1-1/4) = 30 kg.

What's left after giving an A?

(30-2/3)/(1-1/3) = 44 kg

4. Xiao Wang, Xiao Li and Ding Xiao do business in partnership, and each of them will pay dividends at the end of the year. Xiao Wang took 1/3 of the total profit plus 90,000 yuan, Xiao Li took the remaining 1/3 plus 1.2 million yuan, and Ding Xiao took the remaining 1.3 and the remaining 1.2 million yuan after taking a small part. How much do they each get?

This topic is unclear, such as "Xiaoding took the small gist and took the rest 1/3", who is the "small gist"; I don't understand "surplus 1/3, surplus1.2000 yuan".

If the meaning of the question is clear, it should be as easy to understand as the above question.
