Answer 2

\(\frac{15.7-15.4}{10.3}\)

\(=\frac{15.\left(7-4\right)}{10.3}\)

\(=\frac{15.3}{10.3}\)

\(=\frac{15}{10}=\frac{3}{2}\)

Answer 3

15 . 7 - 15 . 4 / 10 . 3 = 15 . ( 7 - 4 ) / 10 . 3

                                  = 15 . 3 / 10 . 3

                                  = 3 . 1 / 2 . 1 = 3/2

Answer 4

\(\frac{15.7-15.4}{10.3}\)

= \(\frac{15.\left(7-4\right)}{10.3}\)

= \(\frac{15.3}{10.3}\)

= \(\frac{3}{2}\)
