3/5 div 12/5 *-4 =-1

Explanation:

When dividing two fractions, you can flip the second fraction around and thus change the division to a multiplication. You can then simplify the expression by cancelling out numbers.

3/5 div 12/5 *-4

= 3/cancel(5) * cancel(5)/12 *-4

= 3 * 1/12 *-4

= -cancel(12)*1/cancel(12)

=-1
