Answer:
To arrange the decimal numbers 0.0023, 0.23, and 0.023 in descending order, compare the digits in each decimal place starting from the left. In descending order, the numbers are 0.23, 0.023, and 0.0023.
Step-by-step explanation:
To arrange the decimal numbers in descending order, we need to compare the value of each number.
The given numbers are 0.0023, 0.23, and 0.023.
To compare them easily, look at the decimal place values: tenths, hundredths, thousandths, etc.
The number with the largest value in the left-most decimal place will be the largest number.
The number 0.23 has '2' in the tenths place, which is the largest compared to '0' in the tenths place of the other numbers.
Next is 0.023, which has '2' in the hundredths place, followed by 0.0023, which has '2' in the thousandths place.
Therefore, in descending order, the numbers are 0.23, 0.023, and 0.0023.
