Question: Type the missing number.
Hint: Use properties of multiplication.
1 × ? = 726
(1) 725
(2) 726
(3) 729
(4) 722
Solution:
REMEMBER : Identity property:
Multiplying by 1 does not change a number.
To find the missing value, use properties of multiplication to make both sides of the equation look the same.
The identity property says multiplying by 1 does not change a number.
1×? = 726
? = 726
Now match up the two sides of the equation.
? = 726
So, the missing value is 726.
Then the option is (2).
