Question 357490
First, add {{{11/15}}} and {{{7/10}}}



For more help with fractions, see <a href="http://www.algebra.com/algebra/homework/NumericFractions/fractions-solver.solver">this solver</a>.


*[invoke fractions_solver 11, 7, "+", 15, 10]



Since {{{11/15+7/10=43/30}}}, this means that 



{{{11/15+7/10-2/5=43/30-2/5}}}



So let's now evaluate {{{43/30-2/5}}}



*[invoke fractions_solver 43, 2, "-", 30, 5]

Answer:


So {{{11/15+7/10-2/5=31/30}}}
