Question 1019764
.
What is the solution and answer of "1/3-(-2/7)"
---------------------------------------------------


<pre>
{{{1/3}}} - {{{(-2/7)}}} = {{{1/3}}} + {{{2/7}}} =    (write fractions with common denominator)

= {{{7/21}}} + {{{6/21}}} = {{{(7+6)/21}}} = {{{13/21}}}.


When manipulate with fractions (adding, distracting), always write them with the common denominator.
