y : 4/5 + 2/3 = 15/4
y : 4/5 = 15/4 - 2/3
y : 4/5 = 37/12
y = 37/12 x 4/5
y = 37/15
y : 4/5 + 2/3 = 3/4 : 1/5
y : 4/5 + 2/3 = 15/4
y : ( 4/5 + 2/3) = 15/4
y : 22/15 = 15/4
y = 15/4 x 22/15
y = 2/11
\(y:\dfrac{4}{5}+\dfrac{2}{3}=\dfrac{3}{4}:\dfrac{1}{5}\\ y:\dfrac{4}{5}+\dfrac{2}{3}=\dfrac{15}{4}\\ y:\dfrac{4}{5}=\dfrac{15}{4}-\dfrac{2}{3}\\ y:\dfrac{4}{5}=\dfrac{37}{12}\\ y=\dfrac{37}{12}\times\dfrac{4}{5}=\dfrac{37}{15}\)
y: 4/5 + 2/3=3/4 x 5
y: 4/5 + 2/3=15/4
y: 4/5 =15/4 - 2/3
y: 4/5 =45/12 - 8/12
y: 4/5 = 37/12
y = 37/12 x 4/5

tic cho tôi☠
y : 4/5 + 2/3 = 15/4
y : 4/5 = 15/4 - 2/3
y : 4/5 = 37/12
y = 37/12 x 4/5
