Question

please give me correct answer

Answer 1

Answer 3(i).

Given value is 0.642 m

We know that 1m = 10 decimetres

so decimetre value will be = 0.642 * 10 = 6.42 decimetre.

We know that 1m = 100 centimetres

so centimetre value will be = 0.642 * 100 = 64.2 centimetres.

We know that 1m = 1000 milimetres

so milimetre value will be = 0.642 * 1000 = 642 milimetres.

Answer 3(ii).

Given value is 0.023 m

We know that 1m = 10 decimetres

so decimetre value will be = 0.023 * 10 = 0.23 decimetre.

We know that 1m = 100 centimetres

so centimetre value will be = 0.023 * 100 = 2.3 centimetres.

We know that 1m = 1000 milimetres

so milimetre value will be = 0.023 * 1000 = 23 milimetres.

Answer 3(iii).

Given value is 70.507 m

We know that 1m = 10 decimetres

so decimetre value will be = 70.507 * 10 = 705.07 decimetre.

We know that 1m = 100 centimetres

so centimetre value will be = 70.507 * 100 = 7050.7 centimetres.

We know that 1m = 1000 milimetres

so milimetre value will be = 70.507* 1000 = 70507 milimetres.
