Calculate the decimal number for each fraction and identify the ascending numerical order of the decimal numbers:

5/8,1/4, 3/8,2/3,6/7,

To calculate the decimal number for each fraction, divide the numerator by the denominator:

5/8 = 5 ÷ 8 = 0.625
1/4 = 1 ÷ 4 = 0.25
3/8 = 3 ÷ 8 = 0.375
2/3 = 2 ÷ 3 ≈ 0.6667
6/7 = 6 ÷ 7 ≈ 0.8571

Now, let's identify the ascending numerical order of the decimal numbers:

0.25, 0.375, 0.625, 0.6667, 0.8571

To calculate the decimal number for each fraction, divide the numerator by the denominator.

5/8 = 0.625
1/4 = 0.25
3/8 = 0.375
2/3 = 0.66666667 (rounded to 8 decimal places)
6/7 = 0.85714286 (rounded to 8 decimal places)

The ascending numerical order of the decimal numbers is:
0.25, 0.375, 0.625, 0.66666667, 0.85714286

To calculate the decimal number for a fraction, you need to divide the numerator (top number) by the denominator (bottom number). Let's calculate the decimal number for each fraction and then identify the ascending numerical order:

1. 5/8: Divide 5 by 8: 5 ÷ 8 = 0.625
2. 1/4: Divide 1 by 4: 1 ÷ 4 = 0.25
3. 3/8: Divide 3 by 8: 3 ÷ 8 = 0.375
4. 2/3: Divide 2 by 3: 2 ÷ 3 ≈ 0.6667 (rounded to four decimal places)
5. 6/7: Divide 6 by 7: 6 ÷ 7 ≈ 0.8571 (rounded to four decimal places)

Now, let's identify the ascending numerical order of the decimal numbers:

0.25, 0.375, 0.625, 0.6667, 0.8571

Arranging them in ascending order, we get:

0.25, 0.375, 0.625, 0.6667, 0.8571

So, the ascending numerical order of the decimal numbers is: 0.25, 0.375, 0.625, 0.6667, 0.8571.
