Question

a) 0.77 dm: 494.000 km :85.000 dm= m
b) 2230 mm +8470 km+ 22.1 mm = dm
c) 9700 dm+ 73 dam +8290 km= dam
d) 918.000 cm +327.000 dm +9820 cm= cm
e) 280 mm la puterea a 2 +200 m la puterea 2+ 9.5 dm la puterea 2= dm la puterea 2

Answer 1

b) 2230 mm +8470 km+ 22.1 mm = 22,3dm+84.700.000dm+0,221dm=84700022,521dm

c) 9700 dm+ 73 dam +8290 km=97 dam+73dam+829.000dam=829.170dam

d) 918.000 cm +327.000 dm +9820 cm= 918.000cm+3.270.000cm+9820cm=33.627.820cm

e) 280 mm²+200 m²+ 9.5 dm²=0,028 dm²+20.000dm²+9,5dm²=20.009,528dm²
