Take 1 meter as 10 / 10, 2 meters as 40 / 20, 3 meters as 90 / 30; 2 / 5 is equal to 10 / 10, which is a fraction of 1 meter, 2 / 5 is equal to 20 / 20, which is a fraction of 2 meters, 2 / 5 is equal to 30 / 30, which is a fraction of 3 meters; finally, we need to reduce the score, and the result is the result after reduction

Divide the 6-meter-long rope into 7 sections. How many parts of the total length is each section? How many meters is each section?

(1) 1 / 7 = 17; (2) 6 / 7 = 67

Divide a 4-meter-long wood into 5 sections, each section is a fraction of the length of the wood, and each section is a fraction of the length of the wood
I have to hand it in. By the way, there are several questions. 1. There are 26 girls in class 5 (1), 2 less than boys. What's the number of girls? What's the number of boys? What's the number of boys? 2. After facing a rope, facing it again, facing it again, what's the length of each rope? OK, I'll give it to you right away!

Divide a 4-meter-long timber into 5 sections, each section is 1 / 5 of the timber, and each section is 4 / 5 of the timber
1÷5=1/5
4 △ 5 = 4 / 5 (m)
1. There are 26 girls in class 5 (1), 2 less than boys. The number of girls is 13 / 14 of boys, and the number of boys is 14 / 27 of the class
26÷（26+2）=13/14
28÷（26+28）=14/27
2. Face a rope, face it again, and then face it again. Now the length of each rope is one eighth of that of the whole rope
1÷2÷2÷2=1/8
