Answer :

To express [tex]\(0.214\)[/tex] as a fraction, we need to convert the decimal to a fraction and then simplify it.

1. Let [tex]\( x \)[/tex] be the decimal number:

[tex]\[ x = 0.214 \][/tex]

2. Identify the number of digits in the decimal part.

Since 0.214 has three digits after the decimal point, we need to multiply [tex]\( x \)[/tex] by [tex]\( 1000 \)[/tex] to convert it to a whole number.

3. Multiply both sides of the equation by [tex]\( 1000 \)[/tex]:

[tex]\[ 1000x = 214 \][/tex]

4. Express [tex]\( x \)[/tex] as a fraction:

[tex]\[ x = \frac{214}{1000} \][/tex]

5. Simplify the fraction:

To simplify [tex]\( \frac{214}{1000} \)[/tex], we find the greatest common divisor (GCD) of 214 and 1000. The GCD of 214 and 1000 is 2.

[tex]\[ \frac{214}{1000} = \frac{214 \div 2}{1000 \div 2} = \frac{107}{500} \][/tex]

6. Final simplified fraction:

Therefore, the decimal [tex]\( 0.214 \)[/tex] expressed as a fraction is:

[tex]\[ \boxed{\frac{107}{500}} \][/tex]

This gives us the final result that [tex]\( 0.214 \)[/tex] as a simplified fraction is [tex]\( \frac{107}{500} \)[/tex].
