$\frac{-17}{15}$

Step-by-step explanation:

When solving this problem you must follow PEMDAS, so parentheses should go first. To solve 1/10 - 2/3, first, find the common denominator. In this case, that is 30. Then, subtract, $\frac{3}{30} - \frac{20}{30}$ . This equals -17/30. Finally, divide by 0.5. To do this remember that dividing by half is the same as multiplying by 2. Doing $\frac{-17}{30} *2$ equals $\frac{-17}{15}$ .
