Video Solution

Solution Steps

00:04 Let's find the smaller number. Pay attention to each digit.

00:08 Compare the digits carefully, one by one.

00:12 You can always add a zero to the end. It doesn't change the number's value.

00:17 Notice zero is less than one. So, this number is smaller.

00:22 Now, let's check the next number using the same approach.

00:27 This time, three is more than one. So, this number is larger.

00:32 Let's examine the next number again, following the same method.

00:36 The number two is also greater than one. So, it's larger.

00:44 Let's look at the final number.

00:47 We see the numbers are equal!

00:51 And that concludes our problem solving! Well done!

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.
