Question 1134368
A positive integer is one less than another.
a = 2b
 If the sum of the reciprocal of the smaller and twice the reciprocal of the larger is 2,
{{{1/b}}} + {{{2/a}}} = 2
replace a with 2b
{{{1/b}}} + {{{2/(2b)}}} = 2
multiply equation by 2b, cancel the denominators
2 + 2 = 4b
4 = 4b 
b = 1
the
a = 2
