5 out of 6 minus 4 out of 9 multiplied by 9 out of 14. What's the quotient of the product minus 1 out of 6?

5 out of 6 minus 4 out of 9 multiplied by 9 out of 14. What's the quotient of the product minus 1 out of 6?

（5/6-4/9）* 9/14 / （1/6）
The answer is: nine out of four is nine out of four

Given the set M = {a, B}, n = {1,3a}, and M = n, find the value of a and B

If a = 3A, a = 0, so B = 1, if B = 3A, then a = 1, B = 3

Given the set a = {- 1,2}, B = {x | MX + 1 = 0}, if a ∪ B = a, find the value of M

a∪b=a
So B is a subset or an empty set of A
If B is a subset of a, i.e. - 1,2 can satisfy MX + 1 = 0, then M = 1, M = - 1 / 2
If B is an empty set, i.e. MX + 1 = 0, there is no solution, i.e. M = 0
So m = 0,1, - 1 / 2

Given the set M = {a, B}, n = {1,3a), and M = n, find the value of a and B, the detailed process

a=1
3a=b
a=1
b=3
a=3a
b=1
a=0
b=1
Two possibilities

Let a = {X / - 1 ≤ x ≤ 6} B = {X / M-1 ≤ x ≤ 2m + 1}, we know that B is a subset of A
1. Find the value range of real number M;
Why is M-1 > 2m + 1 when B is an empty set

A={x/-1≤x≤6｝
B=｛x/m-1≤x≤2m+1｝
It is known that B is a subset of A
(1) B is not an empty set
-1≤m-1
2m+1≤6
0≤m≤5/2
(2) B is an empty set
m-1＞2m+1
m

M = √ 2013 - √ 2011 n + √ 2012 - √ 2010 compare the size of M and n

1/m=1/(√2013-√2011)=(√2013+√2011)/(2013-2011)=(√2013+√2011)/2;
1/n=1/(√2012-√2010)=(√2012+√2010)/(2012-2010)=(√2012+√2010)/2;
∴1/m＞1/n;m＞0,n＞0;
∴m＜n;
