Meteorology: One measure of average global temperature shows how each year varies from a base measure. The table shows results for several years, see the table and answer the following
a. Order of years from coldest to warmest
b. In 1946, the average temperature varied by - 0.03°C from the base measure. Between which two years should 1946 fall when the years are ordered from coldest to warmest

Solution:

a. According to the given data the order of five years from coldest to warmest is 1964, 1965, 1978, 1958, 2002.

b. In 1946, the average temperature varied by -0.03°C. Since, -0.10°C < -0.03°C < (1/50)°C.

Therefore, 1946 should fall between 1965 and 1978.

✦ Try This: Simplify: [7(1/3) + 8/5] / [3(7/4) ÷ 1/6]

To solve the above problem you can follow the fractions and decimals rules to get the required answer.
