A teacher asks his students to write the numbers shown in order from least to greatest √115, 115/11, and 10.5624 Paul thinks the numbers are already in order. Sandra thinks the order should be reversed. who is right?
Two of the given numbers should be converted to the same format as the third number has. In this case, √115 and 115/11 should be converted to their decimal equivalents with four decimal places:
√115 = 10.7238
115/11 = 10.4545
10.5624
Having done this, we see immediately that the largest number is √115 = 10.7238.
In ascending order, the numbers are: 10.4545, 10.5624 and 10.7238,
