Can you burn fat doing many repetitions with little weight?

The answer is NO, and this applies to men and women, the fact of doing thousands of repetitions with "very low" weights will have little influence on fat burning and this happens because it will not influence a direct fat burning since what was spent during the execution of these thousands of repetitions per hour, it will be intramuscular glycogen, which generates as a product lactic acid (lactate) and for this reason it is that feeling of burning or burning.
