Answer 1

\(73:100-732,6:1000\\ =73:100-73,26:100\\ =\left(73-73,26\right):100\\ =-0,26:100\\ =-\dfrac{13}{5000}\)

Answer 2

73:100-732,6:1000

=0,73-0,7326

=\(\dfrac{-13}{5000}\)

Answer 3

\(73:100-732,6:1000\)

\(=73:100-732,6:10\text{×}100\)

\(=73:100-73,26:100\)

\(=\left(73-73,26\right):100\)

\(=0,26:100=0,0026\)
