a two-digit decimal, its approximate number is 1, and the maximum of this two-digit decimal is 1.4 and the minimum is 9.95.

meaning of approximate number: approximate number refers to a numerical value close to the exact number. In this problem, the approximate number is 1, which means that this two-digit decimal is in the range of 9.95 to 1.4, that is, its value is between plus and minus .5 of 1.

maximum value and minimum value: within a given range, the maximum value is the upper limit of the range and the minimum value is the lower limit of the range. In this problem, the maximum value of this two-digit decimal is 1.4 and the minimum value is 9.95. This means that if the two decimal places are as close to 1 as possible, its value may be 1.4 or 9.95.

how to get the approximate number: the method to get the approximate number of a number is usually rounding. In this problem, since the two decimal places are between 9.95 and 1.4, its approximate number is 1. If we want to express this number more accurately, we can use its actual value. For example, we can say that the two decimal places are 9.96 or 1.3, instead of simply saying that it is 1.

accuracy problem: approximation numbers may introduce accuracy problems. In this problem, because we only know that the approximate value of this two-digit decimal is 1, we can't determine its exact value. If we want to get more accurate results, we should use its actual value instead of approximate value.

Application scenarios of approximate number with two decimal places in real life:

1. Weather forecast: The approximate number is often used in weather forecast to represent meteorological data such as temperature and precipitation. For example, the forecaster may say that the highest temperature today is about 3 degrees and the lowest temperature is about 2 degrees. These approximate numbers can help people understand the recent weather conditions, so as to make corresponding clothes and travel preparations.

2. Sports competition: In sports competition, it is often necessary to use the approximate number to count the results of the competition. For example, in a basketball game, the score may be calculated by rounding to the nearest integer, so as to determine the winning team after the game. These approximate numbers can help referees and spectators better understand the results of the game.

3. Financial investment: When making financial investment, people usually need to use the approximate number to estimate the investment return and risk. For example, fund managers may use approximate numbers to estimate the rate of return in the next few months, so that investors can make more informed investment decisions. These approximate numbers can help investors better understand the investment risks and returns, so as to make more reasonable investment choices.
