So we would solve this like

As the first fraction is a mixed fraction so to solve it we need to first convert it to an improper fraction!

 

$$1\frac{3}{4}$ $divided $ by$\frac{1}{2}$$   ( so now to convert the first fraction to an improper one we will multiply 4 by 1 and then add 3 to it)

 

$$=\frac{7}{4}$ divided by$$ $$\frac{1}{2}$$  ( And now we will reciprocate the second or the fraction on the right side and also change the division sign to multiplication one)

 

$$=\frac{7}{4}*\frac{2}{1}$$  ( and now we will cross multiply them)

 

$$=\frac{7}{2}$$    ( we have got this after we had cut 2 and 4 , and now we can transform this into two forms which will then give us our two types of answers)

 

$$=3\frac{1}{2}$$   $$ANSWER$$  ( answer as a mixed fraction)

or

 

$$=3.5$$  $$ANSWER$$  ( answer in decimal form)

 

i hope u have understood by now but if not then pls be free to ask!

i hope this helps!

there are lots of ways to do it but I wil show you the most formal way. 

$$1 \frac{3}{4} \div \frac{1}{2}\\\\
= \frac{4*1+3}{4} \div \frac{1}{2}\\\\
= \frac{7}{4} \div \frac{1}{2}\\\\
\mbox{When you are dividing by a fraction your have to invert(turn the second one upside down) and multiply}\\\\
= \frac{7}{4} \times \frac{2}{1}\\\\
= \frac{14}{4} \\\\
= 3\frac{2}{4} \\\\
= 3\frac{1}{2} \\\\$$
