Question

12 7/25+ 7 23/25
*All fractions, not division*

Answer 1

let's firstly convert the mixed fractions to improper fractions.

`\stackrel{mixed}{12(7)/(25)}\implies \cfrac{12\cdot 25+7}{25}\implies \stackrel{improper}{\cfrac{307}{25}} ~\hfill \stackrel{mixed}{7(23)/(25)}\implies \cfrac{7\cdot 25+23}{25}\implies \stackrel{improper}{\cfrac{198}{25}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{307}{25}~~ + ~~\cfrac{198}{25}\implies \cfrac{307~~ + ~~198}{25}\implies \cfrac{505}{25}\implies \cfrac{101}{5}\implies 20(1)/(5)`
