Answer 1

Iată rezolvarea corectă a egalităţilor enumerate:
2m+ 6dm= ? cm
2m= 200cm 6dm= 60cm
200cm+ 60cm= 260cm

3m+ 2cm= ? cm
3m= 300cm
300cm+ 2cm= 302cm

1dm+ 4cm= ? mm
1dm= 100mm 4cm= 40mm
100mm+ 40mm= 140mm

1m- 1dm= ? dm
1m= 10dm
10dm- 1dm= 9dm

9dm+ 7dm= ? cm
9dm= 90cm 7dm= 70cm
90cm+ 70cm= 160cm

3cm+ 5mm= ? mm
3cm= 30mm
30mm+ 5mm= 35mm

2m- 2cm= ? cm
2m= 200cm
200cm- 2cm= 198cm

3cm- 6mm= ? mm
3cm= 30mm
30mm- 6mm= 24mm

5cm- 5mm= ? mm
5cm= 50mm
50mm- 5mm= 45mm
Sper să-ţi fie de folos! ^-^
