Can you add an irrational number and a rational number

Let `a` be a rational number and `b` be an irrational number,assume that the sum is rational.

1.a +b =c

Where a and c are rational and b is irrational.

2.b=c-a

Subtracting the same number a from each side.

3.b is irrational c-a is a rational number we arrived at a contradiction.

So the sum is an irrational number.

Is a rational number an irrational number

No rational number is an irrational number.

6.4 and 6.40 equivalent or not equivalent

yes these are equivalent

How do you determine whether an expression is rational algebraic expression or not

If the algebraic expression can be written in the form of a(x)/b(x) where a(x) and b(x) are polynomial functions of x and b(x) ≠ 0, then the expression is a rational algebraic expression.

Is 6 a rational or irrational number

4.6 is rational.

Would pie be an irrational number

Why the sum difference and product of 2 rational numbers rational

A rational number is one that can be expressed as a/b

The sum of two rational numbers is:

a/b + c/d

=ad/bd + bc/bd

=(ad+bc)/bd

=e/f

which is rational

The difference of two rational numbers is:

a/b - c/d

=ab/bd - bc/bd

=(ab-bc)/bd

=e/f

which is rational

The product of two rational numbers is:

(a/b)(c/d)

=ac/bd

=e/f

which is rational
