Answer 1

7:2 = 7/2

1,25 x2 = 2,5

1,28 x 4 = 5,12

59:2=59,2

Answer 2

\(7:2=3,5\)

\(1,25\times2=2,5\)

\(1,28\times4=5,12\)

\(59:2=29,5\)

Answer 3

\(7\div2=3\) dư \(1\),  \(7\div2=\dfrac{7}{2}\) hoặc \(7\div2=3,5\)

\(1,25\times2=2,5\)

\(1,28\times4=5,12\)

\(59\div2=29\) dư \(1,59\div2=\dfrac{59}{2}\) hoặc \(59\div2=29,5\)
