Question

Va rog faceți cat puteți măcar 2-3 exerciți

Answer 1

1.a)0,805 g= 80,5 cg
1 g......100 cg
b)43,2 mg=4,32 cg
2. a)360 secunde=6*60 secunde=6 minute
b)540 sec=60*9 =9 minute
3.2020-an bisect
=> 29 zile *24 ore=696 ore
4.3500 dg+2,78 dag= 3,5 hg+0,278 hg=4,778 hg

Answer 2

1)
0,805 g=80,5 cg
43,2 mg=4,32 cg
2)
1 minut=60 secunde
360 secunde=360:60=6 minute
540 secunde=540:60=9 minute
3)
2020 va fi an bisect=>29 zile×24 h=696 h
4)
3500 dg=3,5 hg
2,78 dag=0,278 hg
3,5 hg+0,278 hg=3,778 hg
5)
V=10³=1000 m³
1 m³...................................725 kg
1000 m³....................................x
x=1000×725=725000 kg=725 tone
6)
0,55×60 minute=33 minute
18 h 35 minute+1,55 minute=18 h 35 minute+1 h 33 minute=19 h 68 minute=20 h 8 minute
