Question

I need help for my math in the image please explain your answer.

Answer 1

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.

Answer 2

Directions: Solve each question and show your work.

1. Select all the ways that express the number 32.148.

A. 32 tens + 14 tenths + 8 hundredths

=32*10+14/10+8*1/100

=321.48

B. 32 ones + 14 hundredths + 8 thousandths

=32+14*1/100+8*1/1000

=32.148

C. 321 tenths + 48 thousandths

=321*1/10+48*1/1000

=32.148

D. 32,148 hundredths

=32,148*1/100

=321.48

E. 32,148 thousandths

=32,148*1/1000

=32.148

Answer is B,C and E.

2. Express the number 78.263 using ones, tenths, and thousandths.

a. 78 ones + 263 thousandths

b. 7 tenths + 8263 thousandths

c. 78263 thousandths

3. The teacher asked the class, "How many tenths are equivalent to 37.6?" Student 1 answered, "37 tenths." Student 2 answered, "376 tenths." Which student is correct and why? Explain your answer.

solution Given;

Student 1 answer = 37 tenths=37*1/10=3.7

Student 2 answer =376 tenths =376*1l10=37.6

Student 2 is current because student 1 answer is not equal to 37.6.
