Hello

[blissful star]

hi

[muted crypt]

To solve this first

you need to know the length of the coin

which is?

[blissful star]

2.8 cm?

[muted crypt]

Yes

Now for problem a we need to find the number of coins right?

[blissful star]

yes

[muted crypt]

how can you do that if you have the length of a single coin, and the total length?

(how many single coins go into the total distance?)

[blissful star]

so what i would do is

since it is 560 cm long

i would do 560/2.8

[muted crypt]

Yes

[blissful star]

bc 2.8 is the length of 1 coin

[muted crypt]

Yeah

and then what?

[blissful star]

so 560/2.8 is 200

[muted crypt]

Ok so there are 200 coins

but what is the question asking for?

[muted crypt]

Is the answer the number of coins?

that what i meant

[blissful star]

oh

no its asking for the value

[muted crypt]

Ok so what will the value be?

[blissful star]

so we multipy by 2?

[muted crypt]

Yes

[blissful star]

wich gives us 400?

[muted crypt]

Yes 400 pounds

(make sure to include unit in answer)

[blissful star]

its already put

[muted crypt]

Ok good

[blissful star]

but i need answer for b

[muted crypt]

Now you have the value of coins right?

[blissful star]

yes

[muted crypt]

but we dont need the value we need the number?

so how can you get the number of coins

[blissful star]

since the value (in Question b) is 600, we need to divide by 2?

[muted crypt]

Yes

so how many coins

[blissful star]

which gives us 300 coins

[muted crypt]

Now you know the number of coins and the distance of one coin

[blissful star]

but then i coin length is 2.8cm

so we do 300/2.8

no wait

thats wrong

[muted crypt]

Good,

what is it

[blissful star]

wait so we do 300/2.8?

[muted crypt]

No its wrong

you were right

You have the number of coins and the coin length

how do you get the total

[blissful star]

yh i dont know about that

[muted crypt]

Ok well remember the first question

you started with the total distance

and you divided it by the length to get the number of coins

so

[blissful star]

we do it backwards?

[muted crypt]

Do you know how to use equations?

[blissful star]

nah

[muted crypt]

$number of coins = \frac{total distance}{distance of single coin}$

well if you look at this

[blissful star]

so ur saing

saying*

[muted crypt]

how can you rearrange this to get the total distance?

[hoary fossil]

imdeadinside4630

[blissful star]

num of coins x distance of single coin?

[muted crypt]

Yes

[blissful star]

so 300 * 2.8?

[muted crypt]

Yes

whats the answer?

[blissful star]

840 cm?

[muted crypt]

yes

good job

[blissful star]

YOO @muted crypt THANK U SO MUCH
