Question

Add:
(a) 750 cm and 550 cm. Write the sum in mm.
(b) 4252 cm and 50 dm. Write the sum in m.​

Answer 1

Step-by-step explanation:

In this activity you will convert between metric

units of length:

kilometres, metres, centimetres, and millimetres.

1 km = 1000 m

1 m = 100 cm

1 m = 1000 mm

1 cm = 10 mm

Think about

how to change from one unit to another.

A kilometre is one thousand metres! so km m

or m km

A millimetre is a thousandth of a metre! so mm m

or m mm

A centimetre is one hundredth of a metre! so cm m

or m cm

Think about

how to use this to help you change to different units … and back again ….

Answer 2

Answer:

(1cm = 10mm)

750×10 = 7500mm

550×10=5500mm

Now add

7500+5500

=13000 Ans

I Hope this help you :)
