Answer: i think 3
Explanation:
To find the missing digit in the multiplication problem 34 x □5, we need to determine what number should replace the blank space.
To solve this, we can use basic multiplication principles.
First, let's look at the units digit. When multiplying any number by 5, the units digit of the product will always be either 0 or 5. Therefore, the units digit of the missing number is either 0 or 5.
Next, let's consider the tens digit. In this case, it's 4. To find the tens digit of the product, we need to multiply the tens digit of the multiplicand (3) by the missing digit. If we multiply 3 by 5, we get 15, which means the tens digit of the product is 5. However, if we multiply 3 by 0, we get 0, which means the tens digit of the product is 0.
Therefore, we have two possible answers: 305 and 345. Both of these numbers are valid options for the missing digit in the multiplication problem 34 x □5.
