Answer 1

Răspuns:

a ) 952 cl

b ) 797 l

c ) 640 cl

Explicație pas cu pas:

a )

340 ml = 34 cl

9 l = 900 cl

34 cl + 18 cl + 900 cl = 52 + 900 = 952 cl

b )

9000 ml = 9 l

830 dl = 83 l

889 l - 9 l - 83 l = 880 - 83 = 797 l

c )

8 l = 800 cl

58 dl = 580 cl

1200 ml = 120 cl

980 cl - 800 cl + 580 cl - 120 cl = 180 + 580 - 120 = 760 - 120 = 640 cl.
