Question

7*3=( *3)/(4*3)
Need to find the missing number before the *3

Answer 1

the missing number is 84

Explanation:

Let the missing number be represented by N. Then we have ...

7*3 = N*3/(4*3)

Canceling common factors on the right, we have ...

7*3 = N/4

Multiplying by 4 gives ...

4*7*3 = N = 84

The missing number is 84.
