Answer 2

Answer:

There are 21 marbles in total.

Step-by-step explanation:

Consider the provided information.

Fin has 7 bags of marbles each bag has 3 marbles .

We need to Show one way to break apart the seven to multiply them.

7 can be break in several ways, Let break 7 bags as 4 bags and 3 bags.

7 bags = 4 bags + 3 bags

Each bag has 3 marbles

$3\times 7=3(4+3)$

Now distribute 3 inside the parentheses.

$3\times 7=3\times 4+3\times 3$

$3\times 7=12+9$

$3\times 7=21$

Hence, there are 21 marbles in total.
