$-\frac{7}{10}$

1. Absolute value means a number that is always positive, so the absolute value of negative numbers turn positive, and the absolute value of positive numbers stay positive. Therefore, the absolute value of $-\frac{7}{10}$ is $\frac{7}{10}$. 2. There is a negative outside the absolute value sign so it turns the entire number negative, $-\frac{7}{10}$
