2m+10dm=.....cm 3kg +400gram=...ons

1m = 100 cm
1dm = 10 cm

2(100) + 10(10)
= 200 + 100
= 300 cm

1 kg = 1000 gram
1 ons = 100 gram

3(1000) + 400
= 3000 + 400
= 3400 : 100
= 34 ons

Semoga Membantu

1. 2meter + 10 Dm =....cm
2×100 cm= 200 cm
10×10Cm=100 cm
jadi 2 meter + 10 Dm= 300 Cm

2. 3kg + 400grm=....ons
3×1000grm : 100ons = 30 ons
400grm : 100 ons= 4 ons
Jadi 3kg + 400grm= 34 ons
