Question

What is the sum of 18 23/30+2/3​

Answer 1

let's firstly convert the mixed fraction to improper fraction and then add them up.

`\stackrel{mixed}{18(23)/(30)}\implies \cfrac{18\cdot 30+23}{30}\implies \stackrel{improper}{\cfrac{563}{30}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{563}{30}~~ + ~~\cfrac{2}{3}\implies \cfrac{(1)563~~ + ~~(10)2}{\underset{\textit{using this LCD}}{30}}\implies \cfrac{563+20}{30}\implies \cfrac{583}{20}\implies 29(3)/(20)`
