Decimal Comparison: Finding Numbers Less Than 0.91

Video Solution

Solution Steps

00:00 Choose the number that is smaller than the given number

00:03 Let's compare the digits of the numbers

00:06 We can always add 0 to the right side of the last digit

00:09 The digit 0 is smaller than 1, therefore the number is smaller

00:14 Let's check the next number, using the same method

00:23 The digit 3 is larger than 1, therefore the number is larger

00:27 Let's check the next number, using the same method

00:32 The digit 2 is larger than 1, therefore the number is larger

00:40 Let's check the next number, using the same method

00:43 We can see that the numbers are equal

00:47 And this is the solution to the question

Step-by-Step Solution

To determine which answer is correct, let's compare the answers and find out which one is less than 0.91:

Let's look at the answers:

0.9 - If we add 0 we get the number 0.90, since the hundredths digit is 0 and 0 is less than 1, this is the correct answer.

0.93 - Since the hundredths digit is 3 and 3 is greater than 1, this is not the correct answer.

0.92 - Since the hundredths digit is 2 and 2 is greater than 1, this is not the correct answer.

0.91 - Since both numbers are equal to each other, this is not the correct answer.
