Answer:
The unknown is 300
Step-by-step explanation:
Given the question :
long division setup showing an incomplete calculation. 15 is in the divisor, 6396 is in the dividend, and 4 hundreds and 2 tens is written in the quotient. 6000 is subtracted from 6396 to give 396. An unknown value represented by a box is being subtracted from 396
The unknown is derived by multiplying the obtained quotient by the divisor, then subtracting it from the remaining Dividend.
Since the remaining Dividend is 396, and the obtained quotient is 2 tens (20). Then (divisor × quotient) = (15 × 20) = 300.
The steps can be found in the explanation attached below
