Question

[Tạ Vương Ánh Nguyên]

Y + 4/11 : 15/21 = 19/5

Answer 1

[Cao Văn Phong]

y + \(\dfrac{4}{11}\) : \(\dfrac{15}{21}\) = \(\dfrac{19}{5}\)

y + \(\dfrac{4}{11}\) x \(\dfrac{21}{15}\) = \(\dfrac{19}{5}\)

 y + \(\dfrac{28}{55}\) = \(\dfrac{19}{5}\)

y          = \(\dfrac{19}{5}\) - \(\dfrac{28}{55}\)

y         = \(\dfrac{181}{55}\)
