Question

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

100 POINTS

Answer 1

1) B,C ,E

3) Second student.

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*$ (1)/(100)+ 8*(1)/(1000)$}`

= 32 + 0.14 + 0.008

= 32.148

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

= 32.1 + 0.048

= 32.148

`\sf E) \text{32148 thousandths=32148*$(1)/(1000)$}`

= 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* (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.
