What is the order of 75%, 1/3, 3/8, and 0.625 from least to greatest?
Sophie [7]

Answer: Least To Greatest: 1/3, 3/8, 0.625, 75%.

Step-by-step explanation: If you want to find these values in order from least to greatest, then you‘ll have to find each of their values in either decimal form or fraction form, but I recommend converting them to decimal form. 1/3 = 0.33333, 3/8 = 0.375, 0.625, 75% = 0.75. So, now you can arrange them in order, just remember to re-convert them to the form they were originally in.
