Match the columns in the following: Column A Column B (a) 1 decimetre (p) 1 1000 kilometer (b) 1 centimetre (q) 1 10 metre (c ) 1 millimetre (r) 1 100 metre (d) 1 metre (s) 1 1000 metre

We know that, 1 decimeter = 10 centimeters 10 centimeter = 0 .1 metre Thus, 1 dm = 0 .1 m = 1 10 m 1 metre = 100 centimetre Thus, 1 centimetre = 0 .01 m = 1 100 m . 1 metre = 1000 millimetres 1 mm = 1 1000 m Thus, 1 mm = 1 1000 m 1 kilometre = 1000 metres 1 m = 1 1000 km Thus, 1 m = 1 1000 km . Column A Column B (a) 1 decimetre (q) 1 10 metre (b) 1 centimetre (r) 1 100 metre (c ) 1 millimetre (s) 1 1000 metre (d) 1 metre (p) 1 1000 kilometer

Length of the nail — 2 c m and _____ m m or 2 . _____ c m .

Given, To find the length, measure using ruler. Length of nail = 2 c m 9 m m Now, 10 m m = 1 c m 1 m m = 1 10 c m 9 m m = 0.9 c m So, 2 c m 9 m m = 2.9 c m Therefore, length of nail is 2 . 9 cm .

Match the columns in the following: Column A Column B (a) 65 mm (p) 6500 cm (b) 65 km (q) 0 .65 m (c) 65 cm (r) 6 .5 cm (d) 65 m (s) 65000 m

We know that, 1 cm = 10 mm . 65 mm = 65 10 cm = 6 .5 cm , Thus, 65 mm = 6 .5 cm . 1 km = 1000 m . 65 km = 65 × 1000 m = 65000 m , Thus, 65 km = 65000 m . 1 cm = 1 100 m . 65 cm = 65 100 m = 0 .65 m Thus, 65 cm = 0 .65 m 1 m = 100 cm 65 m = 65 × 100 cm = 6500 cm Thus, 65 m = 6500 cm . Column A Column B (a) 65 mm (r) 6 .5 cm (b) 65 km (p) 6500 cm (c) 65 cm (q) 0 .65 m (d) 65 m (s) 65000 m Therefore, according the conversions the units are matched as shown above.
