10 cm in 1 dm.. then just convert it.. for example: 70 cm = 1dm/10cm = 7 dm... what i did there was 70 x 1 / 10 = 7 dm
50 cm equals to 0.5, or half a meter. A full meter is 100 cm.
70cm
700 mm =70 cm =7 dm =0.7 m
1 dm= 10 cm 1 hm= 100m .'. I think it's 0.7hm ? not sure
It is 1.4 cm and 0.6 cm.
35:45 ratio can be simplified by dividing both numbers by 5 to get 7:9 ratio.
