\boldsymbol{\sf{(4)/(5)+(9)/(10) } }

The least common multiple of 5 and 10 is 10. Convert 4/5 and 9/10 to fractions with denominators of 10.


\boldsymbol{\sf{(4*2)/(5*2)+(9)/(10) \ \ \to \ \ Simplify }}


\boldsymbol{\sf{ (8)/(10)+(9)/(10) }}

Since 8/10 and 9/10 have the same denominator, join their numerators to add them.


\boldsymbol{ \sf{(8+9)/(10) \ \to \ \ Add }}

Simplify


\boldsymbol{\sf{ (17)/(10)= }}\boxed{\boldsymbol{\sf{1(7)/(10) }}}
