\(\dfrac{2}{3}+\dfrac{3}{4}:3=\left(\dfrac{2}{3}+\dfrac{3}{4}\right):3=\left(\dfrac{8}{12}+\dfrac{9}{12}\right):3=\dfrac{17}{12}:3=\dfrac{17}{36}\)
\(\dfrac{2}{3}+\dfrac{3}{4}:3=\dfrac{2}{3}+\dfrac{1}{4}=\dfrac{8}{12}+\dfrac{3}{12}=\dfrac{11}{12}\)
2/3+3/4:3=2/3+3/4x1/3=2/3+1/4=11/12 tick mik nha
2/3 + 3/4 : 3
= 2/3 + 1/4
= 8/12+3/12
= 11/12
