Nine groups of 8 students and one group of 6 students. 9 x 8 = 72. 78 - 72 = 6.
1/3 because 4 to 12 can be written as 4/12 which can be simplified to 1/3
And 1/3 of 6 is two and if you reverse the process you would 4 into 12 three times and then find what goes into 6 three times with is 2
The answer is 1561 yuans and 27 jiao.
