Question

Answer 1

\(g,0,4+\left(-2\dfrac{4}{5}\right)=\dfrac{2}{5}+\left(\dfrac{-14}{5}\right)=\dfrac{-12}{5}\)

\(h,-4,75-1\dfrac{7}{12}=\dfrac{19}{4}-\dfrac{19}{12}=\dfrac{57}{12}-\dfrac{19}{12}=\dfrac{38}{12}=\dfrac{19}{6}\)

Answer 2

g: =2/5-2-4/5=-2/5-2=-12/5

h: =-19/4-1-7/12

=-57/12-12/12-7/12

=-76/12=-19/3

Answer 3

\(g,=\dfrac{2}{5}-\dfrac{14}{5}=\dfrac{-12}{5}\\ h,=-\dfrac{19}{4}-\dfrac{19}{12}=\dfrac{-19.3-19}{12}=-\dfrac{19}{3}\)

Answer 4

g) = \(0,4+\left(\dfrac{-14}{5}\right)=\dfrac{4}{10}+\left(\dfrac{-14}{5}\right)=\dfrac{2}{5}+\left(\dfrac{-14}{5}\right)=\dfrac{-12}{5}\)

h) = \(-4,75-\dfrac{19}{12}=\dfrac{-19}{4}-\dfrac{19}{12}=\dfrac{-57}{4}\)

Answer 5

g, 0,4 + (-2 4/5)

= 0,4 + (-6/5)

= -4/5

h, -4,75 - 1 7/12

= -4,75 - 19/12

= -19/3
