Hm... Well, we have:
x = 9m + 2 = 12n + 2
So, try finding the smallest positive integer solution of 9m + 2 = 12n + 2.

Basically the children are put into a type of rectangle formation with sides x and y.

In the first one they gave one side as 9 and because of that an extra 2 were left over, if we let columns (the other side of the rectangle) equal to "a" then we get the equation 9a + 2.

Then again 12 rows and "b" columns (if the rows change then the columns change) with again and extra 2 members, 12b + 2.

Notice how they both are equal as they are the same children

9a + 2 = 12b + 2.

Find the smallest value and you get the least amount of children.

can u draw it

#

pls

#

i cant picture it

Oh

#

so how do i find out a

lucid fractal so how do i find out a

You have to write it as an equation.

#

Number of children = (9 x a) + 2.

lucid fractal Apr 10, 2024, 5:45 PM

#

Oh

#

So how do i solve 9a + 2 = 12b + 2

willow moon Apr 10, 2024, 5:46 PM

#

They asked you to find the lowest value.

lucid fractal Apr 10, 2024, 5:46 PM

#

of what

#

a?

willow moon Apr 10, 2024, 5:46 PM

#

Of the number of children.

#

So the lowest value of 9a + 2 or 12b + 2.

#

Find the ratio between a and b.

lucid fractal Apr 10, 2024, 5:47 PM

#

huh

#

wdym

willow moon Apr 10, 2024, 5:47 PM

#

9a + 2 = 12b + 2.

lucid fractal Apr 10, 2024, 5:47 PM

what do i do with it

willow moon Apr 10, 2024, 5:47 PM

Cancel +2.

lucid fractal Apr 10, 2024, 5:48 PM

#

9a - 2

#

Whats that supposed to be

willow moon Apr 10, 2024, 6:13 PM

#

willow moon 9a + 2 = 12b + 2.

We can write this as 9a = 12b.

#

And the a = 12b/9.

#

And lastly a = 4b/3.

willow moon Apr 10, 2024, 6:22 PM

#

willow moon And lastly a = 4b/3.

We need to find the smallest values for "a" and "b".

#

We can see the "4b/3" term can be turned into an integer with b = 3 and with that we get a = 4.

#

9a + 2 = (9 * 4) + 2 = 38.

#

12b + 2 = (12 * 3) + 2 = 38.

#

Hence the smallest number of children is 38.

O

#

couldnt u just find the lowest common multiple between 9 and 12

#

then add 2

#

36+2

Yes

Hm, true. Though, I don't think that will work if the remainders are different.

Oh ok thanks
