Solution Steps

00:00 Choose the larger number from the given number
00:03 Let's compare the digits of the numbers
00:07 We can always add 0 to the right side of the last digit
00:10 The digit 6 is less than 7, therefore the number is smaller
00:15 Let's check the next number using the same method
00:22 The digit 6 is less than 7, therefore the number is smaller
00:27 Let's check the next number using the same method
00:32 We can see that the numbers are equal
00:35 Let's check the next number using the same method
00:39 The digit 1 is greater than 0, therefore the number is larger
00:43 And this is the solution to the question

Step-by-Step Solution

In order to know what the correct answer is, first let's add 0 to the number in the following way:

0.7=0.70 0.7=0.70

Let's look at the answers:

0.699 - If we add another 0 to our number and compare between 0.700 and 0.699, since the tenths digit is 6 and 6 is less than 7, this is not the correct answer.

0.69 - Since the tenths digit is 6 and 6 is less than 7, this is not the correct answer.

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

0.71 - Since the hundredths digit is 1 and 1 is greater than 0, this is the correct answer.

Answer

0.71 0.71
