Question

Samuel has a collection of toy cars. His favorites are the 27 red ones, which make up 60% of his collection. How many toy cars does Samuel have?

Answer 1

I already know the answer and how to get it in cross multiplication form, but how do I write this question in algebraic form?

Answer 2

the answer is 45.

Answer 3

Yep ! What do you mean by algebraic form ?

Answer 4

\[\frac{ 27 }{ 60 } \frac{ x }{ 100 }\]

Answer 5

X = 27 x 100 ÷ 60
X = 45

Answer 6

how would i write the question into an algebraic form now? That's all I want to know if you know.

Answer 7

oh i didn't read what you wrote. now i did.

Answer 8

something like 27x = 60

Answer 9

or something like that.

Answer 10

not even sure how to write it.

Answer 11

I think you already wrote it somewhere above. It would look like (60/100)*x - 27 =0

Answer 12

It's not an emoticon at the end btw that's 'equal zero'.

Answer 13

hm

Answer 14

i think you're right.

Answer 15

what if i did 60% ÷ 3 = 20% x 5 = 100%
so 27 ÷ 3 x 5 = 45

Answer 16

do you get what i did?

Answer 17

Nope.

Answer 18

i turned the 27 (60%) into 20% then i multiplied it by 5 to get 100%, because 20 x 5 = 100%

Answer 19

A lot of numbers you introduced do not exist on the initial problem.

Answer 20

All i did was write the problem in another way 60% * x = 27 so 60% *x - 27 = 0
I don't get why you would do what you did.

Answer 21

how did you do that? Like how did you know to write the problem like that?

Answer 22

that is what I initially wanted to know lol.

Answer 23

pls respond

Answer 24

how did you know to write the problem in that way?

Answer 25

27 cars represent 60% of his collection, and x represents 100% of his collection.
So 60% * x =27 that's how you get it.

Answer 26

.60x = 27
.60 ÷ .60 = 1
27 ÷ .60 = 45
X = 45

Answer 27

ahhh I get it now.

Answer 28

Writing in algebraic form means finding a function 'f' so that f(x)=0. That's why I wrote it that way.

Answer 29

? function? lol your speaking to me in chinese

Answer 30

You haven't study functions yet ?

Answer 31

no ><

Answer 32

studied*

Answer 33

Oh ok :P

Answer 34

didn't learn that yet :P

Answer 35

Is it hard?

Answer 36

Right now, I'm just learning basic algebra.

Answer 37

Not really, no.

Answer 38

Hmm..

Answer 39

how far away am I from learning functions?

Answer 40

wait, i don't even need to worry about that stuff right now lol.

Answer 41

Yeah :p and good luck n your studies !

Answer 42

wait, so the way you wrote it the problem what is it called? like for example the first way I did it was called the cross multiplication method.

Answer 43

wait, what do you mean good luck? you think i need luck? lol

Answer 44

I'm sure you don't :3

Answer 45

what makes you think that?

Answer 46

Well you got the problem right the first time. Anyways I'm out, have a good day !

Answer 47

ok thanks a lot bye :)

Answer 48

Welcome !
