means one half
Similarly, \frac{5}{10} means 5 tenths
<h3>Therefore Option C is also correct</h3>Thus the wrong option is B
<em><u>Justification:</u></em>
5 hundredths can be written as:
Therefore option B is wrong
For this case suppose that we have a quadratic equation of the form:
The solution to the quadratic recuacion is given by:
