Find the missing digits.
- C
- D
C169 - 29D4 = 4195(a)
In the hundreds place, 1 is less than 9.
So, there is regrouping in the thousands place.
C - 1 - 2 = 4
C = 4 + 2 + 1
C = 7
(b)
In the ones place, 9 is more than 4.
So, there is no regrouping in the tens place.
6 - D = 9
In the tens place, 9 is more than 6.
This means that there is a regrouping done in the hundreds place so that 16 can substract a certain number to get 9.
D = 16 - 9
D = 7
Answer(s): (a) 7; (b) 7
