Find the missing digits.
- H
- K
H847 - 72K6 = 2551(a)
In the hundreds place, 8 is more than 2.
So, there is no regrouping in the thousands place.
H - 7 = 2
H = 2 + 7
H = 9
(b)
In the ones place, 7 is more than 6.
So, there is no regrouping in the tens place.
4 - K = 5
In the tens place, 5 is more than 4.
This means that there is a regrouping done in the hundreds place so that 14 can substract a certain number to get 5.
K = 14 - 5
K = 9
Answer(s): (a) 9; (b) 9
