Which of these numbers is the smallest number?
a
74 321
b
743 210
c
7 432 102
d
74 321 020
e
7 432.65
The smallest number is e (7 432.65) because it is the only number with a decimal point.
To determine which of these numbers is the smallest number, we need to compare the numbers digit by digit, starting from the left.
Considering the given numbers:
a) 74,321
b) 743,210
c) 7,432,102
d) 74,321,020
e) 7,432.65
Comparing the numbers digit by digit, we can see that the first digit of each number will determine the smallest number:
a) 7
b) 7
c) 7
d) 7
e) 7
Since all the first digits are 7, we need to compare the second digit:
a) 4
b) 4
c) 4
d) 4
e) 4
Again, all the second digits are the same. We continue comparing the digits until we find a difference:
a) 4
b) 4
c) 4
d) 4
e) 4
At the third digit:
a) 3
b) 3
c) 3
d) 3
e) 2
Finally, we can see that the third digit of choice 'e' is the smallest among the given options, making it the smallest number.
Therefore, the smallest number is '7,432.65', option e.
