Explanations:
1. Number 1 explains when you go left to right, what is the first place that doesn't look the same as the others, that is the tenths because it has a 3 and a 8, they are not the same numbers.
2. I am a bit confused on this one, I am 60% sure it's correct, The difference of the tenths place from question one comes to question 2, 0.3 represents tenths, 0.8 represents tenths, it's the first difference and it's a decimal one place behind the decimal. -Hope you understand.
3. When you line up 0.8 and 0.3, you see 8 is bigger than 3, it's true. 0.8 is the bigger decimal.
4. When you line up the decimals your looking for the smaller one, 3 is smaller than 8, correct. 0.3 is smaller than 0.8.
5. for the first comparison, _ > _, for the first empty box, it's saying put the larger number first, 0.8, 0.8 > _, then put the smaller number, 0.8 > 0.3, then for the second comparison, switch the numbers and symbol! 0.3 < 0.8.
6. First, line up the decimals, Tens and Ones are the same, but the tenths are not, 8 is bigger than 3, so, 17.884 > 17.397.
7. (Easy Trick!) They want to trick you into thinking 0 is a valued number, actually, 0 isn't a integer or a whole number, it also has No value. You can automatically take away the 0. Then, you have 1.53 and 1.53, which are equal. So, 1.53 = 1.53.
8. First, line up the decimals, you see the Tens, Ones, Tenths, and Hundredths are the same, but the thousandths aren't the same. A 5 is greater than a 2. So, 46.635 > 46.632.
9. You can cross off the zeroes. We have .886, and .688, when you line both numbers up, we see that in the tenths place, 8 is greater than 6, that is correct. So, 0.886 > 0.688.
10. First, line up the decimals, we see that Tens, Ones, and Tenths are equal, now compare the numbers in the hundredths place, 3 is greater than 2. So, 29.22 < 29.23.
11. First, line up the decimals. We see that the Ones and Tenths are equal. Let's look at the hundredths place, a 5 is greater than a 4. So, 7.645 < 7.654.
12. You can cross off the zeroes. Second, line up the decimals. We can see that the Tenths place is equal, we should check the Hundredths place, a 5 is greater than a 4. So, 0.55 > 0.542.
13. First, line up the decimals. We can see that the Tens, Ones, and the Tenths are equal. We should check the Hundredths place, a 3 is greater than a 0. So, 82.003 < 82.03.
Best of Luck to you!
