Mathematical breakthrough (fill in the blanks, require writing process) 1.100 meters, add 1 / 5 of it, then subtract 1 / 5 meters, the result is________ rice 2. A pile of coal weighs three fourths of a ton. One fourth of a ton is used for the first time, and the rest is left______ Tons, the second time to use the remaining 1 / 3, the second time to use_____ ton 55 points=______ Time

1.100*(1+1/5)-[100*(1+1/5)](1-1/5)=1/5*100*(1+1/5)
2.3 / 4 * (1-1 / 4) use the previous empty answer * 1 / 3
3.55/60=11/12

Answer to question 7 on page P20 of mathematics exercise book for the second semester of grade 6 of Shanghai Education Press
Fill in the output number in the flow chart on the right. If the input number is 3 / 5, - 4 / 11, then the output number is

Waiting for me
All right, all right, all right
=79 out of 110
Not a positive number, output directly
believe me
I'm Xueba
Also, it tells us to calculate the number already in brackets
It's one, and it says it's a positive number multiplied by a negative one
So there are two answers
79 out of 110 and 1 out of 7
