Question

Write the following values in ascending order (smallest to largest):
0.1, 0.09, 2%,7/10,19/100

Answer 1

First step is to convert all the numbers in a unified mesure
In this case put all the numbers over 100
10/100 (0.1),
9/100 (0.09),
20/100 (2%),
70/100 (7/10),
19/100 (19/100).
Then order them using the base 10 system
9/100, 10/100, 19/100, 20/100, 70/100

Answer: 0.09, 0.1, 19/100, 2%, 7/10
