SET 4: Question 1 of 8
How many dm are there in 4.5 m?
Type in all zeros, eg 0.00000673
dm
There are 45 dm in 4.5 m.
1 dm = 10-1 m
Thus:
1 metre is 100 times ie 10 times larger than a decimetre.
10-1
4.5 m = 4.5 x 10 dm = 45 dm
No, that is not the correct answer.

SET 4: Question 2 of 8
How many mm are there in 7.2 m?
Type in all zeros, eg 0.00000673
There are 7200 mm in 7.2 m.
1 mm = 10-3m
Thus:
1 metre is 100 times ie 103 times larger than a millimetre.
10-3
7.2 m = 7.2 x 1000 mm = 7200 mm
No, that is not the correct answer.

SET 4: Question 3 of 8
How many m are there in 6.5 dm?
Type in all zeros, eg 0.00000673
There are 0.65 m in 6.5 dm.
1 dm = 10-1m
Thus:
1 decimetre is 100 times ie 101 times smaller than a metre.
10-1
6.5 dm = 6.5 / 10 m = 0.65 m
No, that is not the correct answer.

SET 4: Question 4 of 8
How many m are there in 25 mm?
Type in all zeros, eg 0.00000673
There are 0.025 m in 25 mm.
1 mm = 10-3m
Thus
1 centimetre is 100 times ie 103 times smaller than a metre.
10-3
25 mm = 25 / 1000 m = 0.025 m
No, that is not the correct answer.

SET 4: Question 5 of 8
How many cm are there in 1 dm?
Type in all zeros, eg 0.00000673
There are 10 cm in 1 dm.
1 dm = 10-1m
1 cm = 10-2m
Thus
1 decimetre is10-1times ie 101times larger than a centimetre.
10-2
1 dm = 1 x 10 cm = 10 cm
No, that is not the correct answer.

SET 4: Question 6 of 8
How many mm are there in 2.5 dm?
Type in all zeros, eg 0.00000673
There are 250 mm in 2.5 dm.
1 dm = 10-1m
1 mm = 10-3m
Thus:
1 decimetre is 10-1 times ie 102 times larger than a millimetre.
10-3
2.5 dm = 2.5 x 100 mm = 250 mm
No, that is not the correct answer.

SET 4: Question 7 of 8
How many dm are there in 70 cm?
Type in all zeros, eg 0.00000673
There are 7 dm in 70 cm.
1 dm = 10-1m
1 cm = 10-2m
Thus:
1 centimetre is 10-1 times ie 101 times smaller than a decimetre.
10-2
70 cm = 70 / 10 dm = 7 dm
No, that is not the correct answer.

SET 4: Question 8 of 8
How many dm are there in 85 mm?
Type in all zeros, eg 0.00000673
There are 0.85 dm in 85 mm.
1 dm = 10-1m
1 mm = 10-3m
Thus:
1 millimetre is 10-1 times ie 102 times smaller than a decimetre.
10-3
85 mm = 85 / 100 dm = 0.85 dm
No, that is not the correct answer.
