Question

Put the following numbers in order from least to greatest.

A. 12.39, 12.62, 12 5/8, 12 3/4
B. 12.39, 12 5/8, 12.62, 12 3/4
C. 12 5/8, 12.39, 12.62, 12 3/4
D. 12 3/4, 12 5/8, 12.62, 12.39

Answer 1

By converting the fractions to decimals, the numbers ordered from least to greatest are: 12.39, 12.625 (12 5/8), 12.62, 12.75 (12 3/4). Option B is the correct sequence.

Step-by-step explanation:

To order these numbers from least to greatest, we should convert all of them to decimals to make it easier to compare.

1. 12.39 is already in decimal form.
2. To convert 12 5/8 to a decimal, we divide 5 by 8, which gives us 0.625. So, 12 5/8 is equivalent to 12.625.
3. 12.62 is already in decimal form.
4. To convert 12 3/4 to a decimal, we divide 3 by 4, which gives us 0.75. So, 12 3/4 is equivalent to 12.75.

Putting these decimals in order from least to greatest, we get: 12.39, 12.625 (or 12 5/8), 12.62, 12.75 (or 12 3/4).

Therefore, the correct order is B. 12.39, 12 5/8, 12.62, 12 3/4.
