43/50 is easier because 50 is half of 100
Watch this
43/50. Since 50 is HALF of 100 so we multiply 2 by 50 which is 100. But since we multiplied by 2 for the denominator we have to do the same for the numerator so 43 x 2 is equal to 86.
So we get 86/100 which is 0.86
Answer:
142.85

Answer:
A rational expression that has the nonpermissible values 
and 
is 
.
Step-by-step explanation:
A rational expression has a nonpermissible value when for a given value of 
, the denominator is equal to zero. In addition, we assume that both numerator and denominator are represented by polynomials, such that:
(1)
Then, the factorized form of 
must be:
(2)
If we know that 
, then the rational expression is:
(3)
A rational expression that has the nonpermissible values and is .
Answer:
Lets a,b be elements of G. since G/K is abelian, then there exists k ∈ K such that ab * k = ba (because the class of ab, ![[ab]_K](https://tex.z-dn.net/?f=%20%5Bab%5D_K%20)
is equal to ![[ba]_K](https://tex.z-dn.net/?f=%20%5Bba%5D_K%20)
, thus ab and ba are equal or you can obtain one from the other by multiplying by an element of K.
Since K is a subgroup of H, then k ∈ H. This means that you can obtain ba from ab by multiplying by an element of H, k. Thus, ![[ab]_H = [ba]_H](https://tex.z-dn.net/?f=%20%5Bab%5D_H%20%3D%20%5Bba%5D_H%20)
. Since a and b were generic elements of H, then H/G is abelian.
