1, The full form of RRR is Rate of Return. 

A rate of return (RoR) is the net gain or loss of an investment over a specified time period, expressed as a percentage of the investment’s initial cost. When calculating the rate of return, you are determining the percentage change from the beginning of the period until the end.

2, The full form of RRR is Residual-Resistance Ratio. 

RRR (Residual Resistivity Ratio) is a common index for measuring the quality of a metal. This
paper reviewed the three main methods of measuring alloy RRR, and compared the respective advantages and disadvantages. A new cryocooler based measurement method is proposed. Theoretical
analysis shows this method can measure the resistance at various temperatures. There is no need to
reach the liquid helium temperature (4.20K), as achieving temperatures below 38 K is sufficient to
measure RRR. The analysis is later verified by experimental results, and the results differ little from
PPMS (Physical Property Measurement System) measured results.

3, The full form of RRR is Required Reserve Ratio. 

The reserve requirement (or cash reserve ratio) is a central bank regulation that sets the minimum amount of reserves that must be held by a commercial bank. The minimum reserve is generally determined by the central bank to be no less than a specified percentage of the amount of deposit liabilities the commercial bank owes to its customers. The commercial bank’s reserves normally consist of cash owned by the bank and stored physically in the bank vault (vault cash), plus the amount of the commercial bank’s balance in that bank’s account with the central bank.

4, The full form of RRR is Relative Risk Reduction. 

In epidemiology, the relative risk reduction (RRR) or efficacy is the relative decrease in the risk of an adverse event in the exposed group compared to an unexposed group. It is computed as , where is the incidence in the exposed group, and is the incidence in the unexposed group.

5, The full form of RRR is Risk Retention Reporter. 

Risk Retention Reporter (RRR) is a journal for news and analysis for the risk retention industry.

6, The full form of RRR is Raroia Airport. 

Raroia Airport is an airport on the atoll of Raroia, part of the Tuamotu Archipelago in French Polynesia. The airport is adjacent to the village of Garumaoa. It is not approved for night operations, and there are no hangars or repair facilities.

7, The full form of RRR is Reduce, Reuse, Recycle. 

Reduce, Reuse, Recycle (RRR) is a waste management method designed to reduce the use of environmental resources and humans’ carbon footprint on earth.

Reduce, Reuse, Recycle — Three great ways YOU can eliminate waste and protect your environment!

Waste, and how we choose to handle it, affects our world’s environment—that’s YOUR environment. The environment is everything around you including the air, water, land, plants, and man-made things. And since by now you probably know that you need a healthy environment for your own health and happiness, you can understand why effective waste management is so important to YOU and everyone else. The waste we create has to be carefully controlled to be sure that it does not harm your environment and your health.

8, The full form of RRR is Reverse Repo Rate. 

Reverse repo rate is the rate at which the central bank of a country (Reserve Bank of India in case of India) borrows money from commercial banks within the country. It is a monetary policy instrument which can be used to control the money supply in the country.
