What is the difference between the fractions? Use the number line to help find the answer.

NNADVOKAT [17]

Answer:

The difference is $\frac{3}{10}$

Step-by-step explanation:

We must find the common denominator of the fractions.

The common denominator of $\frac{1}{2}$ and $\frac{1}{5}$ is $2*5=10$ ; therefore we have

$\frac{1}{2}=\frac{5}{10}$

$\frac{1}{5} =\frac{2}{10}$

now it is easy to subtract $\frac{5}{10} -\frac{2}{10}$ using the number line: we have to move $\frac{3}{10}$ units to the left in order to get to $\frac{2}{10}$ .

Thus our answer is

$\boxed{\frac{1}{2} -\frac{1}{5}=\frac{3}{10} }$
