Qiqi bought three math stories and spent 24 yuan. How much is each math story? Here is the sum of known mathematical stories.
Equation:
Let the math story be X yuan, then the math fairy tale is 4/5 (4/5) X yuan.
X+4/5 (four fifths) X=27
1.8X=27
X= 15
Because the math story is 15 yuan and the math fairy tale is 27- 15= 12.
