Given the numerical statement:
5×743=(_×700)+(_×40)+(_×3)
Explanation:
It is the same as multiplying the given 5 to each value of 700, 50, and 3, since they are all added afterward. This can be proven by solving the equation.
Solution:
5 x 743 = 3715
(_×700)+(_×40)+(_×3)
(5 × 700)+(5 × 40)+(5 × 3)
= 3500 + 200 + 15
= 3715
The value is the same therefore, the missing number is 5.
