Question

In a race , Ram covers 5 km in 20 min. How much distance will he cover in 100 min ?

Answer 1

Do you know how to create proportions?

Answer 2

No

Answer 3

Okay, so we know that 5km=20 minutes, so x km, equals 100 min
So, we could write
5/20 = x/100
Yea?

Answer 4

Okay yes

Answer 5

Okay, well, because 5/20 can be simplified, it'd be easier if we could first simplify that.
What would it be?, what can 5/20 be simplified to

Answer 6

So, 520 = 5÷520÷5 = 14 520 is equivalent to 14 in the reduced form.

Answer 7

I-
no

Answer 8

It's a fraction, 5/20
Then nevermind

Answer 9

We can cross multiply to find x

Answer 10

Nope

Answer 17

Answer 18

I think that I first have to explain to her what a variable is, and what is x

Answer 19

u really dont have to do dat if u use simple math

Answer 20

A variable is something that stands in for an unknown number
Well, usually a number

Answer 21

okay

Answer 22

For example
x+3=5
yoou could do, x oc is 2, but, technically, to find x, you should subtract 3 from each side, to result x=2

Answer 23

and a number times x, is just _x
ex. 5 times x is 5x
5y times x is 5xy

any letter can be a variable, what we usually use x, and then y, and then z

Answer 24

oh okay
