how to done it please tell it​

Answer 1

We know that,

1 m= 100cm. So,

16m 78cm = 16. 78m and

20m 12cm= 20.12m

So if we add them,

16.78 + 20.12 = 36.90 m

Subtracting this from 40m ,

40 - 36.9= 3.1 m

Therefore,

ANS : 3.1 m

Answer 2

Answer: 400 cm

Step-by-step explanation:

first add like this: 16m 78cm

                           +20m 12cm

                         ____________

                           = 3 6  m    9 0 cm

then subtract like:-1m = 100 cm

                               36 m = 3600cm

               then :- 40 m = 4000cm

then:- subtract = 4000cm

                          - 3600cm
