Answer:_______________




 

1)  

 convert;

3.6cm = Answer: 3 cm Answer: 6 mm


SOLUTION 1 :

Remember:

1 centimetre (cm) = 10 millimetres (mm)

Separate the whole number part and decimal part.

3.6 cm = 3 cm + 0.6 cm

Convert the 0.6 centimetres to millimetres.

Multiply:

0.6 × 10 = 6

0.6 cm = 6 mm

Now express the original measurement in centimetres and millimetres:

3.6 cm = 3 cm + 0.6 cm

3.6 cm = 3 cm 6 mm
 



2)  

 convert;

  Answer: 2 m Answer: 50 cm = 250cm 


SOLUTION 1 :

Remember:

1 metre (m) = 100 centimetres (cm)

 Find out how many metres are in 250 centimetres.

 multiply:

2 x 100 = 200

 

2 m = 200 cm

 

Now add this to the centimetre you already have:

200 cm 50 cm = 200 cm + 50 cm

 250 cm = 200cm + 50 cm

 

 



3)  

 Convert. Write your answer as a decimal.

1 cm 8 mm = Answer: 1.8 cm


SOLUTION 1 :

1 centimetre (cm) = 10 millimetres (mm)

Convert the 8 millimetres to centimetres.

Divide:

8 ÷ 10 = 0.8

8 mm = 0.8 cm

Now add this to the 1 centimetres you already have:

1 cm 8 mm = 1 cm + 0.8 cm

1 cm 8 mm = 1.8 cm



4)  

 Convert. Write your answer as a decimal.

1.8 m = Answer: 1 m Answer: 80 cm 


SOLUTION 1 :

1 metre (m) = 100 centimetres (cm)

 

Separate the whole number part and decimal part.

 

1.8 m = 1 m + 0.8 m

Convert the 0.8 metres to centimetres.

Multiply:

0.8 × 100 = 80

0.8 m = 80 cm

Now express the original measurement in metres and centimetres:

1.8 m = 1 m + 0.8 m

1.8 m = 1 m  80 cm

 



5)  

 convert;

505cm = Answer: 5 m Answer: 5 cm


SOLUTION 1 :

Remember:

1 metre (m) = 100 centimetres (cm)

 

Find out how many metres are in 117 centimetres.

 

Divide:

505 ÷ 100 = 5 R 5

There is 5 metre, with 5 centimetres left over.

505 cm = 5 m 5 cm

 



6)  

 convert;

2.2cm = Answer: 2 cm Answer: 2 mm


SOLUTION 1 :

Remember:

1 centimetre (cm) = 10 millimetres (mm)

Separate the whole number part and decimal part.

2.2 cm = 2 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:

2.2 cm = 2 cm + 0.2 cm

2.2 cm = 2 cm 2 mm
 



7)  

 convert;

  Answer: 6 m Answer: 27 cm = 627cm 


SOLUTION 1 :

Remember:

1 metre (m) = 100 centimetres (cm)

 Find out how many metres are in 627 centimetres.

 multiply:

6 x 100 = 600

 

6 m = 600 cm

 

Now add this to the centimetre you already have:

600 cm 27 cm = 600 cm + 27 cm

 627 cm = 600cm + 27 cm

 

 



8)  

 Convert. Write your answer as a decimal.

2 cm 5 mm = Answer: 2.5 cm


SOLUTION 1 :

1 centimetre (cm) = 10 millimetres (mm)

Convert the 5 millimetres to centimetres.

Divide:

5 ÷ 10 = 0.5

5 mm = 0.5 cm

Now add this to the 2 centimetres you already have:

2 cm 5 mm = 2 cm + 0.5 cm

2 cm 5 mm = 2.5 cm



9)  

 Convert. Write your answer as a decimal.

2.1 m = Answer: 2 m Answer: 10 cm 


SOLUTION 1 :

1 metre (m) = 100 centimetres (cm)

 

Separate the whole number part and decimal part.

 

2.1 m = 2 m + 0.1 m

Convert the 0.1 metres to centimetres.

Multiply:

0.1 × 100 = 10

0.1 m = 10 cm

Now express the original measurement in metres and centimetres:

2.1 m = 2 m + 0.1 m

2.1 m = 2 m  10 cm

 



10)  

 convert;

136cm = Answer: 1 m Answer: 36 cm


SOLUTION 1 :

Remember:

1 metre (m) = 100 centimetres (cm)

 

Find out how many metres are in 117 centimetres.

 

Divide:

136 ÷ 100 = 1 R 36

There is 1 metre, with 36 centimetres left over.

136 cm = 1 m 36 cm
