How did you get it ?

Answer 2

And the answer is wrong :(

Answer 3

No, it's not correct..

Answer 4

Simply multiply by 7

Answer 5

Since 56/8 = 7

Answer 6

7 * 3 = 21

Answer 7

See:

y is directly proportional to x

This means that:

\[\large{y \propto x}\]

Answer 8

Now direct proportionality means that I can write it as:

\[\large{y = k x}\]

where, k = proportionality constant

Now, we have:

y = 56 when x = 8

Thus:

56 = k * 8

So, what would be the value of k ?

Answer 9

7 ?

Answer 10

great

Answer 11

Now we have:

x = 3
So:

y = k * 3

Now you know the value of k, so what would be y ?
