Nickname reads a storybook, and on the first day he reads the whole book 1 5 speed tomorrow

1 (80+10) (1-1 5-1 5) = 150 pages.

2 40000 * 5 8 = 25000 pieces.

25000*2-40000=10000 pieces.

3 (16-7) (5 3) = 15 kg.

4 (1-(8 1)) ((8 1 + 10 1)=9 35 days.

5 (4*3-1*4) (4-3)=8 meters.

8+4)*3=36m.

2/5x+10=x-80x=150

16-7=3/5xx=15

Let the speed of A be x for one day and B for y, and work together for z days.

8x=10y

x+y)z+y=8x, and z=4

x/3-4=x/4-1

x=36

ps: The denominator is followed and the numerator is preceded.

1. Set the first day to x.

5x=x+x+10+80

5x=2x+90

3x=90x=30

30*5=150 (page).

10000 (pieces).

3. Oil + barrel = 16 3 5 oil + barrel = 7

3 5 oil = 9

Oil = 15 (kg).

4. Set x days.

1/8+1/10)*x+1/10=1

So x = 4 days.

5. Set the rope x meters.

1/3x-4=1/4x-1

1/12x=3

x=36

1 (80+10) (1-1 5-1 5) = 150 pages.

2 40000 * 5 8 = 25000 pieces.

25000*2-40000=10000 pieces.

3 (16-7) (5 3) = 15 kg.

4 (1-(8 1)) ((8 1 + 10 1)=9 35 days.

5 (4*3-1*4) (4-3)=8(m)8+4)*3=36m.

Looks like I've done it in **

Summary. 30 storybooks read in a month 1 = 30 copies.

There are a total of 120 short stories in this book, and you can read 1 story every day. How many months does it take to read this book? Seek the process.

30 storybooks read in a month 1 = 30 copies.

120 divided by 30 = 4

So it takes four months.

150*1 5=30 (page) ......Day 1.

30*120%=36 (page) ......The next day.

30 + 36 = 66 (page) ......Two days together.

1-1/2-1/4-1/8=1/8

A: On the last day, I will read 1/8 of the book.

On the premise that the speed is constant, the answers are 3 5, 5
