Another example of the hat operator denoting an ...Examples. For example, ⅘ is a ratio and the proportion statement is 20/25 = ⅘. If we solve this proportional statement, we get: 20/25 = ⅘. 20 x 5 = 25 x 4. 100 = 100. Check: Ratio and Proportion PDF. Therefore, the ratio defines the relationship between two quantities such as a:b, where b is not equal to 0.Similarly 1.85 has a z-score of 3.

Since they both have an equal amount of tenths you need to continue. Now we look at the second decimal place. 23.476 has 7 hundredths and 23.451 has 5 hundredths. This means that 23.451 is smaller than 23.476. So the answer from least to greatest is: 19.894, 23.451, 23.476.The = equals symbol is used to show that the values on either side of it are the same.
