10)  

 convert;

  m cm = 616cm 


Answer:_______________




 

1)  

 convert;

387cm = Answer: 3 m Answer: 87 cm


SOLUTION 1 :

Remember:

1 metre (m) = 100 centimetres (cm)

 

Find out how many metres are in 117 centimetres.

 

Divide:

387 ÷ 100 = 3 R 87

There is 3 metre, with 87 centimetres left over.

387 cm = 3 m 87 cm

 



2)  

 Convert. Write your answer as a decimal.

9 cm 1 mm = Answer: 9.1 cm


SOLUTION 1 :

1 centimetre (cm) = 10 millimetres (mm)

Convert the 1 millimetres to centimetres.

Divide:

1 ÷ 10 = 0.1

1 mm = 0.1 cm

Now add this to the 9 centimetres you already have:

9 cm 1 mm = 9 cm + 0.1 cm

9 cm 1 mm = 9.1 cm



3)  

 convert;

8.2cm = Answer: 8 cm Answer: 2 mm


SOLUTION 1 :

Remember:

1 centimetre (cm) = 10 millimetres (mm)

Separate the whole number part and decimal part.

8.2 cm = 8 cm + 0.2 cm

Convert the 0.2 centimetres to millimetres.

Multiply:

0.2 × 10 = 2

0.2 cm = 2 mm

Now express the original measurement in centimetres and millimetres:

8.2 cm = 8 cm + 0.2 cm

8.2 cm = 8 cm 2 mm
 



4)  

 Convert. Write your answer as a decimal.

4.5 m = Answer: 4 m Answer: 50 cm 


SOLUTION 1 :

1 metre (m) = 100 centimetres (cm)

 

Separate the whole number part and decimal part.

 

4.5 m = 4 m + 0.5 m

Convert the 0.5 metres to centimetres.

Multiply:

0.5 × 100 = 50

0.5 m = 50 cm

Now express the original measurement in metres and centimetres:

4.5 m = 4 m + 0.5 m

4.5 m = 4 m  50 cm

 



5)  

 convert;

  Answer: 8 m Answer: 26 cm = 826cm 


SOLUTION 1 :

Remember:

1 metre (m) = 100 centimetres (cm)

 Find out how many metres are in 826 centimetres.

 multiply:

8 x 100 = 800

 

8 m = 800 cm

 

Now add this to the centimetre you already have:

800 cm 26 cm = 800 cm + 26 cm

 826 cm = 800cm + 26 cm

 

 



6)  

 convert;

103cm = Answer: 1 m Answer: 3 cm


SOLUTION 1 :

Remember:

1 metre (m) = 100 centimetres (cm)

 

Find out how many metres are in 117 centimetres.

 

Divide:

103 ÷ 100 = 1 R 3

There is 1 metre, with 3 centimetres left over.

103 cm = 1 m 3 cm

 



7)  

 Convert. Write your answer as a decimal.

2 cm 4 mm = Answer: 2.4 cm


SOLUTION 1 :

1 centimetre (cm) = 10 millimetres (mm)

Convert the 4 millimetres to centimetres.

Divide:

4 ÷ 10 = 0.4

4 mm = 0.4 cm

Now add this to the 2 centimetres you already have:

2 cm 4 mm = 2 cm + 0.4 cm

2 cm 4 mm = 2.4 cm



8)  

 convert;

5.1cm = Answer: 5 cm Answer: 1 mm


SOLUTION 1 :

Remember:

1 centimetre (cm) = 10 millimetres (mm)

Separate the whole number part and decimal part.

5.1 cm = 5 cm + 0.1 cm

Convert the 0.1 centimetres to millimetres.

Multiply:

0.1 × 10 = 1

0.1 cm = 1 mm

Now express the original measurement in centimetres and millimetres:

5.1 cm = 5 cm + 0.1 cm

5.1 cm = 5 cm 1 mm
 



9)  

 Convert. Write your answer as a decimal.

9.2 m = Answer: 9 m Answer: 20 cm 


SOLUTION 1 :

1 metre (m) = 100 centimetres (cm)

 

Separate the whole number part and decimal part.

 

9.2 m = 9 m + 0.2 m

Convert the 0.2 metres to centimetres.

Multiply:

0.2 × 100 = 20

0.2 m = 20 cm

Now express the original measurement in metres and centimetres:

9.2 m = 9 m + 0.2 m

9.2 m = 9 m  20 cm

 



10)  

 convert;

  Answer: 6 m Answer: 16 cm = 616cm 


SOLUTION 1 :

Remember:

1 metre (m) = 100 centimetres (cm)

 Find out how many metres are in 616 centimetres.

 multiply:

6 x 100 = 600

 

6 m = 600 cm

 

Now add this to the centimetre you already have:

600 cm 16 cm = 600 cm + 16 cm

 616 cm = 600cm + 16 cm
