Lesson Steps

Step	Type	Explanation	Answer
1	Problem	Find the missing value: ? × 212 = 212 × 78
2	Step	The given equation is	? × 212 = 212 × 78
3	Step	We can rearrange the numbers using the commutative property:	212 × 78 = 78 × 212
4	Step	Now, we can see that the missing value must be 78:	? = 78
5	Step	So, the missing value is 78.
6	Choice.A	TThis option is the correct answer. It repres\ents the missing value in the equation. When we divide both sides by 212, we find that the missing value is indeed 78	78
7	Choice.B	This option is incorrect. 16536 is the product of 212 and 78, not the missing value in the equation	16536
8	Choice.C	This option is incorrect. 212 is one of the given numbers in the equation, not the missing value	212

Problem

Find the missing value:
? × 212 = 212 × 78

Step

The given equation is

? × 212 = 212 × 78

Step

We can rearrange the numbers using the commutative property:

212 × 78 = 78 × 212

Step

Now, we can see that the missing value must be 78:

? = 78

Step

So, the missing value is 78.

Choice.A

TThis option is the correct answer. It repres\ents the missing value in the equation. When we divide both sides by 212, we find that the missing value is indeed 78

Choice.B

This option is incorrect. 16536 is the product of 212 and 78, not the missing value in the equation

16536

Choice.C

This option is incorrect. 212 is one of the given numbers in the equation, not the missing value

212

Choice.D

This option is incorrect. 290 is not related to the given equation. It seems to be a random number

290
