Answer 1

$3ore=60*3=180 si 3 \frac{1}{2} =3ore+jumatate=\ \textgreater \ 3*60+30=180+30 \\ =210minute$ =180minute$\\ 4,5ore=60*4+50 \\ =180+50 \\ =230minute$$1,25ore=60+25=85minute$$\\ 2 \frac{1}{2} =60*2+30=120+30 \\ =150minute$[tex] \\ b)4min=4*60 \\ =\ \textgreater \ 240secunde \\ 6,5min=6*60+5 \\ =\ \textgreater \ 365secunde \\ 50 \frac{1}{2} =50*60+30*60 \\ =\ \textgreater \ 4.800secunde \\ 2,5ore=2*60*60+5*60 \\ =\ \textgreater \ 7.500secunde[/tex][tex] \\ c)360secunde=0ore,6min,0sec \\ 360minute=6ore,0min,0sec \\ 7.200secunde=2ore \\ 5.400minute=90ore \\ 216.000secunde=60ore[/tex]
