Question

Buna ! As vrea sa ma ajutati putin la o tema la matematica !
1. 23 cm =....... dm
0,73 kg = ...... g
71,5 m = ........cm
7,2 kg +240 kg =.......kg


2 . 3,2 + 1, 6 =
7,2 - 0,4 =
2,3 x 5,1 =
6,03 x 1,2 + 6,13 =
4,17 : 0,2 + 6,35 =

3 Media arimetica a numerelor 56 si 24 .

Answer 1

1) 23 cm=2.3 dm 0.73 kg=730 g 71.5 m=7150 cm 7.2 kg+240 kg=247.2 kg 2) 3.2+1.6=4.87 7.2-0.4=6.8 2.3×5.1=11.73 6.03×1.2+6.13=13.366 4.17÷0.2+6.35=27.2 3) (56+24)÷2=40
