I] Find the difference 7/10-1/2​

Answer 1

$\huge \dag \: \: \: \bf \frac{7}{10} - \frac{1}{2}$

• Taking LCM of denominators, (which we get as 10),

Now,

$\huge\to \sf \: \: \: \: \frac{7 - 5}{10} \: \: \: \\ \\ \\ \sf \huge \to \: \red{\frac{2}{10} }$

• Here, 2/10 is not in simplest form.

Thus,

$\sf \huge \frac{2}{10} \: \to \: \frac{ \cancel2}{5 \times \cancel2} \\ \\ \\ \huge \sf \to \: \: {\frac{\red1}{\red5} }$

Hence,

• Answer should be 1/5.
