Question

if a 30 cm ruler of steel weighs 50 g what will be the weight of a metre scale

Answer 1

50/30*100gm it is 500/3

Answer 2

hey there ,!!

30cm ruler = 50g

when cm is converted into m and g into kg we get ,,

0.3m = 0.050kg

now,

if 0.3m = 0.050kg

than 0.1 = 0.050/0.3 = 0.166.....kg

now , 1 m = 0.166 × 10 = 16.666..... kg

hope it helps !!
