Question

What is 7 & 3/4 minus 3?

Answer 1

first off you'd want to change the mixed fraction to "improper", and then proceed, let's do so,


`\bf \stackrel{mixed}{7(3)/(4)}\implies \cfrac{7\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{31}{4}} \\\\\\ \cfrac{31}{4}~-~3\implies \cfrac{31}{4}~-~\cfrac{3}{1}\impliedby \textit{our LCD is 4}\implies \cfrac{31-12}{4} \\\\\\ \cfrac{19}{4}\implies 4(3)/(4)`

Answer 2

7 & 3/4 minus 3 is 4.75.
