80% = 0.8 = 4/5 , so 80% of x would be 0.8x or 4x/5 .
if N = number then
y = 0.80N
0.8*N
If the number is 'Q' then the expression is: [ 0.26 Q ]

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,
Let the number be x and so the expression is 8x
If you call your number x, the expression would be 5x.
The algebraic expression for three more than a number is: X + 3
