Find the missing digits.
- H
- K
H729 - 41K5 = 2544(a)
In the hundreds place, 7 is more than 1.
So, there is no regrouping in the thousands place.
H - 4 = 2
H = 2 + 4
H = 6
(b)
In the ones place, 9 is more than 5.
So, there is no regrouping in the tens place.
2 - K = 4
In the tens place, 4 is more than 2.
This means that there is a regrouping done in the hundreds place so that 12 can substract a certain number to get 4.
K = 12 - 4
K = 8
Answer(s): (a) 6; (b) 8
