### Theory:

$$12$$ Peanut butter cookies are present in $$1$$ muffin tin.

How many peanut butter cookies must be there in $$4$$ such muffin tin?

There will be a total of  peanut butter cookies.

If there are $$6$$ muffin tin. Then how many peanut butter cookies will be there?

Thus, the number of peanut butter cookies in $$6$$ muffin tin will be

So, to find the total number of peanut butter cookies here, we have multiplied the number of peanut butter cookies in $$1$$ muffin tin by the number of the muffin tin. This is the concept of multiple.
A multiple of a number is defined as a number which is a product of that number and any other whole number.
Example:
1. The multiples of $$2$$ are $$2$$, $$4$$, $$6$$, $$8$$, $$10$$, $$12$$ and so on.
2. The multiples of $$5$$ are $$5$$, $$10$$, $$15$$, $$20$$, $$25$$, $$30$$ and so on.
