1. B, C, E
2. a. 78 ones + 263 thousandths
b. 782 tenths + 63 thousandths
c. 78263 thousandths
3. Student 2 is correct because the tenths place digit in 37.6 is 6, so there are 376 tenths.
Explanation:
Before you read all of this I want to warn you that I’m bad at explaining things so you still might not understand.
#1. The tens place is the digit 3. So, there are 3 tens and choice A would be illuminated. The ones place digit is the digit 2. There is 1 digit before the ones place (3), so there are 32 ones. The digit one is in the tenths place, the digit 4 in the hundredths place, so there are 14 hundredths. 8 is in the thousandths place digit, so there are 8 thousandths. Therefore, choice B is a valid way to express the number 32.148. The tenths place is 1, so there are 321 tenths. The digit for the thousandths place is 8 and the number before it is 4, so there are 48 thousandths. Therefore, choice C is valid. The digit 8 is in the thousandths place value so, there are 32,148 thousandths. D is incorrect and E is correct.
#2. Because 8 is in the ones place. there are 78 ones. 3 is in the thousandths place, so there are 263 thousandths. There are 782 tenths in that number because 2 is in the tenths digit, and there are 63 thousandths because 3 is in the thousandths place value. Since 3 is in the thousandths place, and we haven't used any digit for part C, there are 78263 thousandths.
#3. The tenths place digit in 37.6 is 6, so there are 376 tenths.
