Answer 1

Answer:

a. 1999 cm

Step-by-step explanation:

because 1000 CM is equal to 1 m

and 199 m will be 199000 cm

Answer 2

Given,

Two Length measurements are = 1999cm and 199m

To find,

The lesser measurement.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

First of all, we have to convert both the measurement in same units, in order to compare them with each other.

Now,

1m = 100cm

So, converting the second measurement into centimetre unit :

= 199 metres

= (199×100) cm

= 19900cm

Now,

First measurement = 1999 cm

Second measurement = 19900 cm

It is obvious that,

1999cm < 19900cm

Thus,

First measurement < Second measurement

Hence, 1999cm is the lesser measurement. (option a)
