Choose the number that is less than .
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.
Which decimal number is greater?
Adding zeros to the right of a decimal doesn't change its value! Think of it like money: 0.9 are both 90 cents. The zero just makes comparison easier.
Add trailing zeros to make them the same length! Compare 0.9 and 0.91 by writing them as 0.90 and 0.91, then compare digit by digit.
Move to the hundredths place! For example, when comparing 0.91 and 0.93, both have 9 in tenths, so look at hundredths: 1 vs 3, so 0.91 < 0.93.
Absolutely! On a number line, numbers get larger as you move right. Since 0.9 comes before 0.91, we know .
Line them up by decimal point and add zeros to make equal lengths: 0.90, 0.91, 0.92, 0.93. Now you can easily see which is smallest!
