Answer 2

To expand : decimal number $18.514$

Solution :

• We know that , in the given decimal number place values of numbers are:

         Place value of  $1$ = tens  

         Place value of $8$ = ones  

          Place value of $5$ = tenths

         Place value of $1$ = hundredths

         Place value $4$ = thousands  

• Therefore , to expand decimal number  we multiply given digits by their place value .
• $18.514$   $= 1\times 10 + 8\times 1 + 5\times (\frac{1}{10} )+ 1\times (\frac{1}{10} )^{2} + 4\times (\frac{1}{10}) ^{3}$

                   $= 10 + 8+ 0.5 +0.01 + 0.004$

Hence, expansion of $18.514$ is $10 + 8+ 0.5 +0.01 + 0.004$ .
