Question

4. Express as km using decimals: (1) 5 m (ii) 888 m (iii) 15 km 88 m​

Answer 1

Answer:

Given distances expressed in km are

i) $5$ m = $0.005$ km

ii) $888$ m = $0.888$ km

iii)  $15$ km $88$ m = $15.088$ km  

Step-by-step explanation:

Given : i) $5$ m

          ii) $888$ m

          iii) $15$ km $88$ m

To find :  Express the given distances as km using decimals.  

Solution :

• The given distances are,  

           i)  $5$ m

          ii) $888$ m

          iii) $15$ km $88$ m

• We have to express the given distances as km using decimals.  
• To convert meters into kilometres, we should know the conversion factor.

        $1$ km = $1000$ m

• Now, covert the given distances in meters into kilometres by dividing it by $1000$, we get

i)  $5$ m = $\frac{5}{1000} =0.005$ km

ii) $888$ m = $\frac{888}{1000}$ $= 0.888$ km

iii) $15$ km $88$ m = $15$ km + $\frac{88}{1000}$

                    = $15$ km + $0.088$ km

                    = $15.088$ km

• ∴ Given distances expressed in km are

i) $5$ m = $0.005$ km

ii) $888$ m = $0.888$ km

iii)  $15$ km $88$ m = $15.088$ km
