Question

Which expression shows the number 5.83 decomposed?

5 + 8 + 3
5 + 0.8 + 0.3
5 + 0.8 + 0.03
0.5 + 0.8 + 0.03

Answer 1

think of the places here.
We've got the whole number prior to the decimal, so that rules out the last answer

Answer 2

@Isabella1870 the first choice also wouldn't make sense. Can you tell me why?

Answer 3

i dont know D:

Answer 4

well, 5+8+3 equals 16...not 5.83

Answer 5

because 5, 8, and 3 are all part of the ones place

Answer 6

we are looking for a number in the 1's place, a number in the tenths place (so 0.x) and a number in the hundredths place (0.0x)

**the x is just a placeholder :)

Answer 7

is it B?

Answer 8

ah, close but not quite!

Answer 9

d

Answer 10

We've ruled out the last choice earlier...

Have you read my explanation?

Answer 11

ok

Answer 12

im positive its D is it ?

Answer 13

it is not D

Answer 14

there is nothing in the tens place

Answer 15

so c

Answer 16

Correct. But do you know why?

Answer 17

no

Answer 18

5?

Answer 19

do you see this? in this number the ones place is filled by 5. So you know that your answer has to start with 5 + etc. etc....

That is why the answer cannot be D.

Answer 20

oh

Answer 21

thank you for helping me :)

Answer 22

in this number, here are the places:

5.0 --> ones
0.1 --> tenths
0.04 --> hundredths

so it would be 5.0 + 0.1 + 0.04


and no problem! I want to make sure you understand :)

Answer 23

so if the above shows how 5.14 is broken down, can you see how 5.83 would be broken down?

5.0 --> ones
0.8 --> tenths
0.03 --> hundredths

So it would be 5.0 + 0.8 + 0.03

Answer 24

oh

Answer 25

that is why you get C.

Does that make sense now? @Isabella1870

Answer 26

yes thank you so much

Answer 27

no problem!
