Final answer:
To divide a mixed number, convert it to an improper fraction. Multiply the first fraction by the reciprocal of the second fraction. Simplify the resulting fraction.
Step-by-step explanation:
To divide a mixed number, we first convert it to an improper fraction. In this case, the mixed number is -8 and the fraction is -42. So, -8 becomes -8/1 and -42/1. Dividing these two fractions, we multiply the first fraction by the reciprocal of the second fraction. Thus, (-8/1) ÷ (-42/1) = (-8/1) * (1/-42). Simplifying this expression, we get 8/42 which can be further simplified to 4/21.
