Final answer:
The missing number in the first equation 6 + ___ = 5 + 6 is 5. In the corrected equation (9×_) × 4 = 9 × (2× 4), the missing number is 2.
Step-by-step explanation:
To solve the first problem, 6 + ___ = 5 + 6, we need to find the number that will make both sides of the equation equal. Since 5 + 6 equals 11, we need to add a number to 6 on the left side to get 11. Therefore, the missing number is 5, because 6 + 5 equals 11.
The second problem, (9×_) × 4 = × (2× 4), seems to have a typo. Assuming it should be (9×_) × 4 = 9 × (2× 4), we could determine the missing number. The right side is 9× (2× 4), or 9× 8, which equals 72. Therefore, (9×_) must equal 72 divided by 4, which is 18. So the missing number is 2, because 9× 2 equals 18.
