Consider the equivalence relation R = {( x, y) Ix-y is an integer}.

Vanyuwa [196]

Answer:

[1]=Z the set of integers

[1/2]={r/2| r is an odd integer}

Step-by-step explanation:

Denote by [a] the equivalence class of an element a.

We know that [a]={x|(x,a)∈R}. Then

[1]={x|(x,1)∈R}={x|x-1 is an integer}={x|x-1=k for some k∈Z}

={x|x=k+1 for some k∈Z}={k+1|k∈Z}={...,-2+1,-1+1,0+1,1+1,2+1,...}=Z

For the other class, we have

[1/2]={x|(x,1/2)∈R}={x|x-1/2 is an integer}={x|x-1/2=r for some r∈Z}

={x|x=r+1/2 for some r∈Z}={r+1/2|r∈Z}={...,-2+1/2,-1+1/2,0+1/2,1+1/2,..}

={...,-3/2,-1/2,1/2,3/2,...}={r/2| r is an odd integer}

What is the greatest number of teams can be formed that have the same amount of boys and girls on each team if they have 54 girl

elena55 [62]

The greatest number of teams can be formed that have the same amount of boys and girls on each team is 6

Solution:

Given that there are 54 girls and 84 boys

We have to find the greatest number of teams can be formed that have the same amount of boys and girls on each team

So we have to find the greatest common factor of 54 and 84

When we find all the factors of two or more numbers, and some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor

Let us find the factors of 54 and 84

The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54

The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84

In the above factors list, 6 is the greatest common factor

Then the greatest common factor is 6

So the greatest number of teams can be formed that have the same amount of boys and girls on each team is 6
