(8 x____) x 5 = 8 x ( 20 x 5).. third grade question please help me solve

(8 x____) x 5 = 8 x ( 20 x 5)

(8 x____) x 5 = 800

40n = 800

n = 800/40

n = 20

(8x20)x5=8x(20x5)

To solve this third-grade question, you need to use the associative property of multiplication. According to the property, it doesn't matter how you group the numbers when multiplying; the result will be the same.

In this equation, we have (8 x ____ ) x 5 on the left side and 8 x ( 20 x 5 ) on the right side.

Let's first solve the left side:

(8 x ____ ) x 5

We can ignore the blank at this point and multiply 8 by 5:

8 x 5 = 40

Now we have:

40 x ____

Now let's solve the right side:

8 x ( 20 x 5 )

Inside the parentheses, we multiply 20 by 5:

20 x 5 = 100

Now we have:

8 x 100

Finally, we multiply 8 by 100:

8 x 100 = 800

Therefore, the left side (40 x ____) and the right side (8 x 100) both equal 800.
