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

100 POINTS

Answer 1

Answer:

1) B,C ,E

3) Second student.

Step-by-step explanation:

Tenths = 1/10

hundredth = 1/100

thousandth = 1/1000

1) Answer: B, C, E

$\sf B) \text{32 ones + 14 hundredths + 8 thousands = 32*1 + 14* \dfrac{1}{100}+ 8*\dfrac{1}{1000} }$

                                                                   = 32 + 0.14 + 0.008

                                                                   = 32.148

$\sf C) \text{321 tenths + 48 thousandths=321* \dfrac{1}{10}+48*\dfrac{1}{1000} }$

                                                = 32.1 + 0.048

                                                = 32.148

$\sf E) \text{32148 thousandths=32148* \dfrac{1}{1000} }$

                                = 32.148

2) 78.263

a)   78 ones + 263 thousandths

b) 782 tenths + 63 thousandths

c) 78,263 thousandths

3) Second student has answered correctly.

Reason:

  $\sf 376 \ tenths = 376* \dfrac{1}{10} = 37.6$

Answer 2

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.

a.  78 ones + 263 thousandths

b. 7 tenths + 8263 thousandths

c.  78263 thousandths

3.

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.
