Question 206866
Your  method  is  correct. It  does  often  result  in  larger  numbers.  But,  not  a  problem  with  a  calculator.
.
You  might  also  realize  that  the  whole  number  part  of  the  mixed  number  can  be  considered part  of  an  addition  process. 1 1/2  is  1+1/2.
This  allows  us  to  convert  the  fractional  part  to  a  decimal,  and  then  add  to  the whole  number  part,  ie, 1+1/2 = 1+.5 = 1.5
.
Good  luck  and  keep  up  the  good  work
