Answer:
simple, divide the number by two, round as needed. 6=3x as normal, 5=2.5x as nromal, etc.
Step-by-step explanation:
Answer:
0.2857 is not a rational number.
Step-by-step explanation:
Because rational numbers have to be greater than 1. Decimals are not over 1 so it is not a rational number. Your welcome!
The solution of the expression ( -x²y)/(-xy)² will be ( -1 / y).
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The given expression will be solved as below:-
( -x²y)/(-xy)² = ( -x²y)/(-x²y²)
Divide -x² by -x² it will become -y / y²
= -y / y²
Divide -y by -y² then it will become -1 / y.
= -1 / y
Therefore, the solution of the expression ( -x²y)/(-xy)² will be ( -1 / y).
