Question

proove that
1\2 +1\4 +1\8...=1

Answer 1

Logicly it's obvious, mathematicly please

Answer 2

putting all of the fractions to a common denominator will help to prove this equation.

after some experiments, you would notice that all of those fractions share a common denominator of 8. Hence, the equation can be rewritten as:

4/8 + 2/8 + 1/8 = 8/8.

now it is simply a matter of seeing whether this is correct.
mathematically, 4+2+1=7, and not 8.
Therefore, you can disprove the original equation

hope it helped, cheers

Answer 3
