I'm guessing you mean to find the answer. So find a common denominator, which is 10. You can leave 7/10 alone. Now multiply by 5 on both the numerator and denominator of 1/2. It would be 5/10. Now subtract 7/10-5/10. The answer is 2/10. It can be simplified to 1/5. The answer now would be: 1/5
I hope this helps. :-) 
[tex] \frac{7}{10} - \frac{1}{2} \\ \\ \frac{7x1}{10x1}= \frac{7}{10} \\ \\ \frac{1x5}{2x5}= \frac{5}{10} \\ \\ \frac{7}{10} - \frac{5}{10}= \frac{2}{10} \\ \\ Solution: \frac{2}{10}[/tex]
