You have to make the denominTors even, in this. Case it is 30. So you mutiply the 4 by 3 because you mutiply true 10 by 3 to get 30. So that fraction is now 12/30. Then mutiply the 2 by 2 because the 15 gets multiplied by 2 to get 30. So your equation is now 12/30 - 4/30. And you solve that to make 8/30. Simplify it to get 4/15. 4/15 is the answer. Hope this helps.
[tex] \frac{4}{10} - \frac{2}{15} \\ \\ \frac{2}{5} - \frac{2}{15} \\ \\ LCD = 15 \\ \\ \frac{2 \times 3}{5 \times 3} - \frac{2}{15} \\ \\ \frac{6 - 2}{15} \\ \\ \frac{4}{15} \\ \\ [/tex]

The answer is: 4/15 or 0.2667.
