3/5 + 3/16 + 13/16

Answer 1

\(\dfrac{48}{19}\)

\(\dfrac{8}{5}\)

Answer 2

48/19

8/5

Answer 3

\(\dfrac{13}{19}+\dfrac{18}{19}+\dfrac{17}{19}=\dfrac{48}{19}\)

\(\dfrac{3}{5}+\dfrac{3}{16}+\dfrac{13}{16}=\dfrac{3}{5}+\left(\dfrac{13}{16}+\dfrac{3}{16}\right)=\dfrac{3}{5}+1=\dfrac{8}{5}\)

Answer 4

\(\dfrac{13}{19}+\dfrac{18}{19}+\dfrac{17}{19}=\dfrac{13+18+17}{19}=\dfrac{48}{19}\)

\(\dfrac{3}{5}+\dfrac{3}{16}+\dfrac{13}{16}=\dfrac{48}{80}+\dfrac{15}{80}+\dfrac{65}{80}=\dfrac{48+15+65}{80}=\dfrac{128}{80}=\dfrac{8}{5}\)
