Answer 2

Answer:

2 : 1

Step-by-step explanation:

We know that -

10mm = 1 cm

Therefore,

40 mm = (40 /10 ) cm

           =  4cm   -------------------    Equation i

They have asked us to find the ratio of

40mm :  2cm

We know that in order to find the ratio the units of digits must be the same. Hence by using the Equation i , we get -

4 cm : 2cm

This can be further reduced to

2cm : 1cm or Simply 2 : 1.
