The water depth is exactly 1-2 15-1 10 = 23/30 of the bamboo pole

The length of the bamboo pole is 12 (5 6-23 30) = 12 (25 30-23 30) = 12 2 30 = 180 cm.

Have fun.

The water depth is exactly 23/30 of the bamboo pole, and the length of the bamboo pole is 180 centimeters.

If there's someone, then I won't join in the fun.

The depth of the water is 1 minus 2/15 and subtracting 1/10 is the answer 23/30

In the second question, the length of the rod is x, (5/6 minus 23/30) multiplied by x to equal 12 cm.

Solve x is equal to 180 cm is the rod length.

A: The water depth is exactly 23/30 of the bamboo poleThe bamboo pole is 180 cm long.

Algorithm: What fraction of the water depth is the bamboo pole? 1 minus 2/15 minus 1/10 = 27/30

Do you know how many centimeters are the length of a bamboo pole? 5/6 minus 27/30 = 2/30 12 2 = 6 6 30 = 180

Question 1: If a bamboo pole is regarded as a unit one, subtract 1/1 from 2/15 inserted into the mud and subtract 1/1/10 of the water surface, that is, the water depth accounts for 23/30;

Second question: Divide 12 by 5/6 minus 23/30 of the difference, and the result is 180 centimeters.

1-1/10-2/15 = 23/30

The length of the rod is x5 6-23 30 = 12cm

x=180cm

Two-fifths are inserted into the mud, that is, 13 15 in the water and 13 15 in the water, and 13 15-1 10 = 23 30 in the water when 1/10 is exposed to the water

When the water rises by 12 cm, the water depth is exactly 5/6 of the total length of the bamboo pole, that is, 12 cm is 5 6-23 30 = 1 15 of the bamboo pole

12 cm is 1 15 of the bamboo pole, and the bamboo pole is 12 (1 15) = 180 cm.

I don't know if it's right, don't blame me if it's wrong, you'd better take a look at it.

The basic properties (alphabetical representation) of inequalities are given first

Nature 1: If a>b, then ac >b c

Property 2: If a>b, c>0, then ac>bc (or a>b c) property 3: if a>b, c<0, then ac1) denominates (using the inequality property).

2) Remove parentheses.

3) Shifts (using the property of inequality 1).

4) Merge similar items.

5) Convert the coefficient of the unknown to 1 (using the property of inequality).

Formula: p(b|a)=p(ab)/p(a)

and p(ab)=(2,2) c(5,2)=1 10p(a)=4 c(5,2)=4 10

Molecule 4 refers to: 1+3, 3+5, 1+5+, 2+4 so: p(b|a)=(1/10)/(4/10)=1/4

p（bia）=n（ab）/n（a）=c₂²/（c₂²+c₃²）=1/4

c is that the two taken are even numbers, that is, the number taken from 2 and 4; c is the odd number of both of them, i.e. the number of the formula taken from 1, 3, 5.
