Find the missing digits.
- G
- H
G617 - 64H5 = 2142(a)
In the hundreds place, 6 is more than 4.
So, there is no regrouping in the thousands place.
G - 6 = 2
G = 2 + 6
G = 8
(b)
In the ones place, 7 is more than 5.
So, there is no regrouping in the tens place.
1 - H = 4
In the tens place, 4 is more than 1.
This means that there is a regrouping done in the hundreds place so that 11 can substract a certain number to get 4.
H = 11 - 4
H = 7
Answer(s): (a) 8; (b) 7
