Question

15.8+15.4/12.3

 

Answer 1

15.8+15.4/12.3 = 17.0520325203

Answer 2

\(\frac{15.8+15.4}{12.3}=\frac{15.\left(8+4\right)}{12.3}=\frac{15.12}{12.3}=5\)

Answer 3

\(\frac{15\cdot8+15\cdot4}{12\cdot3}\)

\(=\frac{15\cdot\left(8+4\right)}{12\cdot3}\)

\(=\frac{15\cdot12}{12\cdot3}\)

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

\(=5\)
