(a)
Since 5 in the hundreds place is not enough to subtract 9, we need to regroup and borrow 1 from the thousands place.
So, we need to minus 1 from 7.
G - 1 - 5 = 1
1 + 5 + 1 =
7G =
7(b)
Since 5 in the hundreds place is not enough to subtract 9, we need to regroup and borrow 1 from the thousands place.
So, we can add 10 to 5 so that the sum 15 can be used to subtract 9.
10 + 5 -
H = 9
15 - 9 =
6H =
6 Answer(s): (a) 7; (b) 6
