\(\dfrac{5}{15}+\dfrac{48}{16}=\dfrac{1}{3}+3=\dfrac{1}{3}+\dfrac{9}{3}=\dfrac{10}{3}\)
\(\dfrac{6}{9}:\dfrac{12}{36}=\dfrac{2}{3}:\dfrac{1}{3}=\dfrac{2}{3}\times\dfrac{3}{1}=\dfrac{6}{3}=2\)
\(\dfrac{4}{12}\times\dfrac{56}{14}=\dfrac{1}{3}\times4=\dfrac{4}{3}\)
\(\dfrac{6}{36}+\dfrac{5}{6}=\dfrac{1}{6}+\dfrac{5}{6}=\dfrac{6}{6}=1\\ \dfrac{1}{4}+\dfrac{5}{30}=\dfrac{1}{4}+\dfrac{1}{6}=\dfrac{6}{24}+\dfrac{4}{24}=\dfrac{10}{24}=\dfrac{5}{12}\\ \dfrac{5}{56}+\dfrac{3}{21}=\dfrac{5}{56}+\dfrac{1}{7}=\dfrac{5}{56}+\dfrac{8}{56}=\dfrac{13}{56}\\\dfrac{12}{18}+\dfrac{12}{42}=\dfrac{2}{3}+\dfrac{2}{7}=\dfrac{14}{21}+\dfrac{6}{21}=\dfrac{20}{21} \)
6/36 + 5/6=1/6+5/6=6/6=1
1/4 + 5/30=1/4+1/6=6/24+4/24=10/24=5/12
5/56 + 3/21=5/56=1/7=5/56+8/56=13/56
12/18 + 12/42=2/3+2/7=14/21+6/21=20/21
2 - 5 6 + 3 - 2 8 = 2 . - 5 3 2 + 3 . - 2 4 2 = 2 . - 5 3 + 3 . - 2 4 = 2 . - 125 + 3 . 16 = 2 . 125 + 3 . 16 = 298
\(\dfrac{6}{56}=\dfrac{6:2}{56:2}=\dfrac{3}{28}\)
