Order the numbers from LEAST to GREATEST.7.3, 7 1/2, 7.03, 7.33
Correct Answer
A. 7.03, 7.3, 7.33, 7 1/2
Explanation
The numbers are ordered from least to greatest by comparing the whole numbers first, followed by the decimal parts. Among the given options, 7.03 is the smallest number because it has the smallest decimal part. Next is 7.3, which has a larger decimal part than 7.03. Then comes 7.33, which has the largest decimal part among the given numbers. Finally, 7 1/2 is the largest number because it is a whole number and does not have a decimal part. Therefore, the correct order is 7.03, 7.3, 7.33, 7 1/2.
