toán 5
1045m=..........km........m
678cm=.........m..........cm
1045 m= 1 km 45 m
678 cm= 6 m 78 cm
cho mk nha
1045 m = 1 km 45 m
678 cm = 6 m 78 cm
Viết số thích hợp vào chỗ chấm:
a) 135m = ... dm
342dm = ... cm
15cm = ... mm
b) 8300m = ... dam
4000m = ... hm
25 000m = ... km
c) 1mm = ...cm
1cm = ... m
1m = ... km
`a) 135m = 135 xx10=1350 dm`
`342dm = 342 xx10=3420cm`
`15cm =15xx10=150 mm`
`b) 8300m =8300:10=830 dam`
`4000m =4000 : 100=40 hm`
`25 000m = 25000:1000=25 km`
`c) 1mm = 1:10=0,1cm`
`1cm = 1:100=0,01 m`
`1m =1:1000=0,001km`
Điền số thích hợp vào chỗ chấm: 2dm + 5mm = … mm
A. 25
B. 52
C. 205
D. 502
15m 5mm bang may mm
15 m 5 mm = 15005 mm.
Đúng 100% luôn!
Ai tk cho mình mình tk lại.
Điền số thích hợp vào chỗ trống:
5mm x 4 = mm
5mm x 4 = 20 mm = 2 cm
Số cần điền vào chỗ trống là 2
