Put 0.25 1/3 3/4 & 49% in order from least to greatest

convert all to decimal, then it's easy

0.25 = 0.25
1/3 = 0.33
3/4 = 0.75
49% = 0.49

0.49,

, 49.9%, 0.049

To put the numbers in order from least to greatest, we need to compare their values. Let's examine each number and convert them to a common format for comparison.

1) 0.25: This is a decimal number, and it can be left as it is.

2) 1/3: This is a fraction. To compare it with the decimal number, we can convert it to a decimal. To convert 1/3 to a decimal, divide 1 by 3: 1 ÷ 3 = 0.333...

3) 3/4: This is another fraction. Similarly, we can convert it to a decimal by dividing 3 by 4: 3 ÷ 4 = 0.75

4) 49%: This is a percentage. To compare it with the other numbers, we need to convert it to a decimal. To convert a percentage to a decimal, divide it by 100: 49 ÷ 100 = 0.49

Now that we have all the numbers in decimal form, we can arrange them from least to greatest:

0.25 < 0.333... < 0.49 < 0.75

Therefore, the numbers in order from least to greatest are: 0.25, 1/3 (0.333...), 49% (0.49), and 3/4 (0.75).
