Final answer:
To arrange the rational numbers from least to greatest, convert percentages to decimals and arrange in ascending order. Then, arrange the remaining decimals in ascending order.
Step-by-step explanation:
To arrange the given rational numbers from least to greatest, we need to convert them all to the same format. In this case, we can convert the percentages to decimals.
a. 1, 16%, 0.16
First, convert 16% to a decimal by moving the decimal point two places to the left. 16% becomes 0.16. Now, we have 1, 0.16, and 0.16. Arranging them from least to greatest, we get: 0.16, 0.16, 1.
b. ,0.5, 5.9
Arrange 0.5 and 5.9 in increasing order: 0.5, 5.9.
