Answer:
[tex]\frac{4}{21}[/tex]
Step-by-step explanation:
In order to find the answer you need to find the common denominator of the two fractions multiply the fractions to receive that common denominator and then subtract to find your answer.
[tex]\frac{1}{3} -\frac{1}{7}[/tex]
Find the common denominator:
[tex]CD=21[/tex]
[tex]1\times7=7[/tex]
[tex]3\times7=21[/tex]
[tex]=\frac{7}{21}[/tex]
[tex]1\times3=3[/tex]
[tex]7\times3=21[/tex]
[tex]=\frac{3}{21}[/tex]
[tex]\frac{7}{21} -\frac{3}{21}[/tex]
Subtract numerators
[tex]7-3=4[/tex]
[tex]=\frac{4}{21}[/tex]
Hope this helps.
