Question

d, \(\dfrac{45.16-17}{28+45.15}\)

Answer 1

`a, (45 . 15 + 45 - 17)/(45 . 15 + 28)`

`= (45 . 15 + 28)/(45.  15 + 28)`

`= 1`

Answer 2

\(\dfrac{45.16-17}{28+45.15}\)

\(=\dfrac{45\left(15+1\right)-17}{28+45.15}\)

\(=\dfrac{45.15+45-17}{28+45.15}\)

\(=\dfrac{45.15+28}{45.15+28}\)

\(=1\)
