4. Write the following as metres and centimetres. Example: 124cm = 1m 24cm.
a) 132cm = m cm b) 274cm = m cm c) 165cm = m cm d) 478cm = m cm e) 321cm = m cm f) 224cm = m cm g) 567cm = m cm h) 329cm = m cm i) 402cm = m cm j) 111cm = m cm k) 202cm = m cm l) 400cm = m cm m) 999cm = m cm n) 890cm = m cm o) 24cm = m cm
Adding and Subtracting Metres and Centimetres Adding m and cm
When might you need to add lengths together?
If somebody took one giant step measuring 1m 53cm and then continued forwards taking another giant step measuring 1m 76cm, how would you find out the distance the person had travelled?
You would add the two measurements together. This is how:
First: Then:
Add the centimetres and regroup. Add the metres (Every 100cm = 1m)
m 1
+ 11
cm 53 76
12 9
Now try these: 5.
a) m cm 1
29 + 1 60 6.
a) 1m 34cm + 1m 72cm
b) m cm 2
m 1
+ 1 3
1
cm 53 76
2 9
or or 1m 53cm
+ 1m 76cm 3m 29cm
1
+ 176cm 329cm = 3m 29cm
153cm 1
24 + 1 73
b) 1m 72cm + 2m 36cm
c) m cm 1
98 + 3 81
c) 3m 59cm + 1m 96cm
5.
d) m cm 2
27 + 1 99
e) m cm 5
82 + 2 68
a) 1m 22cm + 2m 17cm = b) 224cm + 3m 85cm = c) 5m 27cm + 194cm =
