Place the following number in order from Least to Greatest.
A. 64.34
B. 64.5
C. 64.17
D. 64.3
Think of these numbers as money. The numbers after the decimal point are pennies.
What order do you think these numbers should be in?
64.5 = 64.50
64.3 = 64.30
To order the numbers from least to greatest, we can compare the digits in each number from left to right. Let's start with the tenths place.
The numbers are:
A. 64.34
B. 64.5
C. 64.17
D. 64.3
Comparing the tenths place:
A. 34
B. 5
C. 17
D. 3
The number with the smallest value in the tenths place is D. 64.3.
Next, let's compare the hundredths place for the remaining numbers:
A. 4
C. 17
The number with the smallest value in the hundredths place is A. 64.34.
Finally, let's compare the whole numbers:
B. 64
C. 64
The numbers have the same value in the whole number place, so we look at the fractional part again.
Comparing the tenths place:
B. 5
C. 17
The number with the smallest value in the tenths place is B. 64.5.
Putting it all together, the numbers in order from least to greatest are:
D. 64.3, A. 64.34, C. 64.17, B. 64.5.
To place the given numbers in order from least to greatest, we need to compare the decimals first and then the whole numbers.
Let's start with the decimals:
- 64.3 is the smallest decimal because it is the closest to 0.
- Next, we have 64.17, which is larger than 64.3 because 17 is greater than 3.
- We also have 64.34, which is larger than 64.17 because 34 is greater than 17.
- Lastly, we have 64.5, which is the largest decimal because 5 is greater than both 3 and 4.
Now let's compare the whole numbers:
- All the numbers have the same whole number, 64, so we don't need to make any changes.
Putting it all together, from least to greatest, the correct order is:
D. 64.3
C. 64.17
A. 64.34
B. 64.5
