If
then we also have
Pairing up the terms, we can find that
consists of 
terms, so there are copies of 
in the sum 
. Then we find an immediate closed form for the sum:
First, convert 17/3 to an improper fraction. 17/3 becomes 5 2/3.
Then convert 5 2/3 to a decimal.
5 2/3 becomes 5.666...
Then convert the decimal to a percent.
5.666... becomes approximately 566.66%
The value of r is -21/9.
The term BODMAS, which stands for brackets of, division, multiplication, addition, and subtraction, might be used to simplify the expression. It specifies how to answer a mathematical expression in a particular order.
-13=r/9+8
-13-8=r/9
-21=r/9
-21/9=r
What is Expressions and Equations?
Algebraic expressions include variables, numbers, and operational signs. Examples include multiplication, division, exponentiation with the natural exponent, addition, and subtraction.
Fractional expression is the name given to division in an algebraic expression with variables.
Rational numbers are those that can be expressed in fractional form.
An algebraic expression is referred to as being irrational if it contains the variable's root or a fractional power with a changeable base.
