Answer:
[tex] \frac{3}{14} [/tex]
Step-by-step explanation:
Find a common denominator, in this case it would be 14.
Multiply the fractions to make the denominator 14.
[tex] \frac{5}{7} \times 2 = \frac{10}{14} [/tex]
[tex] - \frac{1}{2} \times 7 = - \frac{7}{14} [/tex]
Then you subtract.
10-7=3
[tex] \frac{3}{14} [/tex]
