Not sure if this is a math/ statistics question. Reserves are assets you hold, but are not using immediately. There are oil reserves, mineral reserves (like gold reserves) and cash reserves.
I think you need to rephrase the question for a proper answer.
56 is estimated to be 60.
17 is estimated to 20.
No
Estimated to the nearest whole number, it is 31.
There need no be any estimated digit.
Venezuela has the largest oil reserves in Latin America.
Kazakhstan is the CIS nation with the largest oil reserves. It is estimated to have significant oil reserves in the Caspian Sea region.
Libya has the largest supply of oil reserves in North Africa. It is estimated to hold the largest proven oil reserves in Africa.
Australia is the country with the largest uranium reserves.
The Chinese reserves owns an estimated $3.2 trillion dollars. Japan holds another $2 trillion in reserves. These are the two highest grossing Asian nations in reserves.
The largest phosphate reserves in the world are located in Morocco. Morocco is estimated to hold around 50 billion metric tons of phosphate rock reserves, making it a key player in the global phosphate industry.
Saskatchewan's potash deposits are estimated to contain around 6 billion tons of potash reserves.
Proved reserves are the known quantities of fossil fuels that can be extracted with a high degree of certainty using current technology and economic conditions. Potential reserves, on the other hand, represent estimates of recoverable resources that have a lower level of certainty due to factors like exploration and technology limitations. Together, these estimates help in forecasting the remaining amount of fossil fuels that can be extracted in the future.
We have the most of coal as a fossil fuel resource. Coal reserves are estimated to be more abundant and widely distributed compared to oil and natural gas reserves.
Coal is the fossil fuel with the greatest known reserves. It is estimated to be the most abundant fossil fuel resource, with significant reserves located in countries like the United States, Russia, China, and Australia.
Total armed strength was estimated at 46,000 on active duty and 39,000 reserves.
Present estimates of known uranium ore deposits will last another 100 years
