To divide a rational number by another rational number, we need to multiply the first number by the reciprocal of the second number.

The reciprocal of -10/3 is -3/10.

So, -5 ÷ (-10/3) can be rewritten as -5 * (-3/10).

Multiplying these two fractions, we get (-5) * (-3) / (1 * 10) = 15/10.

Simplifying the fraction, we have 15/10 = 3/2.

Therefore, -5 ÷ (-10/3) is equal to 3/2.
