Question
Use reasoning to fill in the missing numbers.
78 × ________ = 780
- 100
- 10
- 1000
- 10000
Hint:
Here we are going to find the missing number . The given equation is 78 x _=780, First let consider missing space to any variable and then divide the whole equation by the small number like 78 to doing LHS 78 to 1 and then the result of RHS is your answer.
The correct answer is: 10
Here , we have to solve 78 x _ = 780 and find the missing number
First ,let us consider missing space to be e,
So we can write that,
78 x e = 780
Dividing both side by 78 ,
=> (78/78) x e = 780/78
=>1 x e = 10
=> e = 10
Therefore, The missing number is 10.
The correct answer is 10.(option (a)).
To find the missing number in any question divided the both LHS and RHS by same number to make LHS value to 1 and also let assume the variable for missing number. And make sure you are dividing correctly. Apply same concept in similar missing number questions.
