Question

12 phần 7 nhân y=16 phần21

Answer 1

\(\frac{12}{7}\).y = \(\frac{16}{21}\)

y              = \(\frac{16}{21}:\frac{12}{7}\)

y              = \(\frac{4}{9}\)

Answer 2

12/7xY=16/21

        Y=16/21:12/7

         Y=4/9

Answer 3

12/7 x y = 16/21

         y = 16/21 : 12/7

        y = 16/21 x 7/12

        y = 2/3

Answer 4

\(\frac{12}{7}\text{ x }y=\frac{16}{21}\)

\(y=\frac{16}{21}\text{ : }\frac{12}{7}\)

\(y=\frac{16}{21}\text{ x }\frac{7}{12}\)

\(y=\frac{4}{9}\)
