Right here we are going to study subtraction of 3-digit numbers utilizing expanded kind.
Specific every quantity in expanded kind, then subtract those, tens and hundred place.
Let’s attempt to clear up the next instance:
1. Subtract 356 from 768.
Resolution:
First we have to categorical the quantity 356 and 768 in expanded kind.
Expanded type of 356
356 = 3 a whole bunch + 5 tens + 6 ones
and
Expanded type of 768
768 = 7 a whole bunch + 6 tens + 8 ones
Now we subtract the expanded kind:
768 = 7 a whole bunch + 6 tens + 8 ones
– 356 = – 3 a whole bunch + 5 tens + 6 ones
Distinction = 4 a whole bunch + 1 ten + 2 ones = 412
Due to this fact, 768 – 356 = 412
2. Subtract 324 from 965.
Resolution:
First we have to categorical the quantity 324 and 965 in expanded kind.
Expanded type of 324
324 = 3 a whole bunch + 2 tens + 4 ones
and
Expanded type of 965
965 = 9 a whole bunch + 6 tens + 5 ones
Now we subtract the expanded kind:
965 = 9 a whole bunch + 6 tens + 5 ones
– 324 = – 3 a whole bunch + 2 tens + 4 ones
Distinction = 6 a whole bunch + 4 tens + 1 ones = 641
Due to this fact, 965 – 324 = 641
3. Subtract 210 from 649.
Resolution:
First we have to categorical the quantity 210 and 649 in expanded kind.
Expanded type of 210
210 = 2 a whole bunch + 1 ten + 0 ones
and
Expanded type of 649
649 = 6 a whole bunch + 4 tens + 9 ones
Now we subtract the expanded kind:
649 = 6 a whole bunch + 4 tens + 9 ones
– 210 = – 2 a whole bunch + 1 ten + 0 ones
Distinction = 4 a whole bunch + 3 tens + 9 ones = 439
Due to this fact, 649 – 210 = 439
4. Subtract 465 from 798.
Resolution:
First we have to categorical the quantity 465 and 798 in expanded kind.
Expanded type of 465
465 = 4 a whole bunch + 6 tens + 5 ones
and
Expanded type of 798
798 = 7 a whole bunch + 9 tens + 8 ones
Now we subtract the expanded kind:
798 = 7 a whole bunch + 9 tens + 8 ones
– 465 = – 4 a whole bunch + 6 tens + 5 ones
Distinction = 3 a whole bunch + 3 tens + 3 ones = 333
Due to this fact, 798 – 465 = 333
