Question

3 × 5/8 + 3,200 ÷ 3?

Answer 1

$\bf 3\times \cfrac{5}{8}+3200\div 3\implies \stackrel{\stackrel{ 3\times \frac{5}{8}}{\downarrow }}{\cfrac{15}{8}}+3200\div 3 \\\\\\ \cfrac{15}{8}+\stackrel{\stackrel{3200\div 3}{\downarrow }}{\cfrac{3200}{3}}\implies \stackrel{\textit{using an LCD of 24}}{\cfrac{(3)15+(8)3200}{24}}\implies \cfrac{45+25600}{24} \\\\\\ \cfrac{25645}{24}\implies 1068\frac{13}{24}$

recall MD are first, from left to right, and lastly AS, also from left to right.
