\(\dfrac{3}{4}+\dfrac{-1}{3}-\dfrac{5}{18}=\dfrac{27}{36}+\dfrac{-12}{36}-\dfrac{10}{36}=\dfrac{5}{36}\)
a) \(0.75+\dfrac{-1}{3}-\dfrac{5}{18}=\dfrac{3}{4}+\dfrac{-1}{3}-\dfrac{5}{18}=\dfrac{5}{12}-\dfrac{5}{18}=\dfrac{5}{36}\)
`0,75 + [-1] / 3 - 5 / 18`
`= 3 / 4 + [-1] / 3 - 5 / 18`
`= 27 / 36 + [ -12 ] / 36 - 10 / 36`
`= 5 / 36`
=\(\dfrac{3}{4}\)+\(\dfrac{-1}{3}\)-\(\dfrac{5}{18}\)
=\(\dfrac{5}{12}\)-\(\dfrac{5}{18}\)
=\(\dfrac{5}{36}\)
