Answer 2

Answer:

Expansion of $178 . 345$  is $100 + 70 + 8 + 0.3 + 0.04 + 0.005$ .

Step-by-step explanation:

To expand : decimal number  178 . 345​

Solution :

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

       Place value of $1$ = hundreds  

       Place value of $7$ = tens  

       Place value of $8$ = units

       Place value of $3$ = tenths

       Place value of $4$ = hundredths

       Place value of $5$ = thousandths

• Therefore , to expand decimal number  we multiply given digits by their place value .

$\begin{aligned}178 .345=(1 \times 100)+(7 \times 10)+(8\times 1 ) + ( 3\times \frac{1}{10} )+ ( 4\times \frac{1}{100})+(5\times\frac{1}{1000}) \end{aligned}$

           $= 100 + 70 + 8 + 0.3 + 0.04 + 0.005$
