80% = 0.8 = 4/5 , so 80% of x would be 0.8x or 4x/5 .
The algebraic expression "twice a number z" can be represented as 2z. In this expression, the variable z represents the unknown number, and multiplying it by 2 gives you twice that number. This expression can be used in algebraic equations and formulas to represent scenarios where a number needs to be doubled.

The Base in the Algebraic Expression can be a Number or A Variable. EX. 42 or X2 - 4 and X are the base.
an algebraic expression is an expression built up from constants, variables, and a finite number of algebraic operations (addition, subtraction, multiplication,division and exponentiation to a power that is a rational number). For example,
The algebraic expression for 84 divided by the number ( z ) is ( \frac{84}{z} ). This expression represents the quotient of 84 and the variable ( z ).
If you call your number x, the expression would be 5x.
