Subtraction of 3-Digit Numbers utilizing Expanded Kind|3 Digit Subtraction

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
