Maths Subtraction Worksheet 6 Grade 3 - Free Printable

The task involves solving a series of subtraction problems. Let's go through each problem step by step.

Problem a: \( 532 - 455 \)

1. Subtract the ones place: \( 2 - 5 \). Since 2 is less than 5, borrow 1 from the tens place (3 becomes 2).
- \( 12 - 5 = 7 \).
2. Subtract the tens place: \( 2 - 5 \). Since 2 is less than 5, borrow 1 from the hundreds place (5 becomes 4).
- \( 12 - 5 = 7 \).
3. Subtract the hundreds place: \( 4 - 4 = 0 \).

So, \( 532 - 455 = 77 \).

Problem b: \( 618 - 939 \)

1. Subtract the ones place: \( 8 - 9 \). Since 8 is less than 9, borrow 1 from the tens place (1 becomes 0).
- \( 18 - 9 = 9 \).
2. Subtract the tens place: \( 0 - 3 \). Since 0 is less than 3, borrow 1 from the hundreds place (6 becomes 5).
- \( 10 - 3 = 7 \).
3. Subtract the hundreds place: \( 5 - 9 \). Since 5 is less than 9, the result will be negative.
- \( 5 - 9 = -4 \).

So, \( 618 - 939 = -321 \).

Problem c: \( 322 - 261 \)

1. Subtract the ones place: \( 2 - 1 = 1 \).
2. Subtract the tens place: \( 2 - 6 \). Since 2 is less than 6, borrow 1 from the hundreds place (3 becomes 2).
- \( 12 - 6 = 6 \).
3. Subtract the hundreds place: \( 2 - 2 = 0 \).

So, \( 322 - 261 = 61 \).

Problem d: \( 846 - 768 \)

1. Subtract the ones place: \( 6 - 8 \). Since 6 is less than 8, borrow 1 from the tens place (4 becomes 3).
- \( 16 - 8 = 8 \).
2. Subtract the tens place: \( 3 - 6 \). Since 3 is less than 6, borrow 1 from the hundreds place (8 becomes 7).
- \( 13 - 6 = 7 \).
3. Subtract the hundreds place: \( 7 - 7 = 0 \).

So, \( 846 - 768 = 78 \).

Problem e: \( 932 - 655 \)

1. Subtract the ones place: \( 2 - 5 \). Since 2 is less than 5, borrow 1 from the tens place (3 becomes 2).
- \( 12 - 5 = 7 \).
2. Subtract the tens place: \( 2 - 5 \). Since 2 is less than 5, borrow 1 from the hundreds place (9 becomes 8).
- \( 12 - 5 = 7 \).
3. Subtract the hundreds place: \( 8 - 6 = 2 \).

So, \( 932 - 655 = 277 \).

Problem f: \( 647 - 528 \)

1. Subtract the ones place: \( 7 - 8 \). Since 7 is less than 8, borrow 1 from the tens place (4 becomes 3).
- \( 17 - 8 = 9 \).
2. Subtract the tens place: \( 3 - 2 = 1 \).
3. Subtract the hundreds place: \( 6 - 5 = 1 \).

So, \( 647 - 528 = 119 \).

Problem g: \( 913 - 251 \)

1. Subtract the ones place: \( 3 - 1 = 2 \).
2. Subtract the tens place: \( 1 - 5 \). Since 1 is less than 5, borrow 1 from the hundreds place (9 becomes 8).
- \( 11 - 5 = 6 \).
3. Subtract the hundreds place: \( 8 - 2 = 6 \).

So, \( 913 - 251 = 662 \).

Problem h: \( 749 - 498 \)

1. Subtract the ones place: \( 9 - 8 = 1 \).
2. Subtract the tens place: \( 4 - 9 \). Since 4 is less than 9, borrow 1 from the hundreds place (7 becomes 6).
- \( 14 - 9 = 5 \).
3. Subtract the hundreds place: \( 6 - 4 = 2 \).

So, \( 749 - 498 = 251 \).

Problem i: \( 297 - 248 \)

1. Subtract the ones place: \( 7 - 8 \). Since 7 is less than 8, borrow 1 from the tens place (9 becomes 8).
- \( 17 - 8 = 9 \).
2. Subtract the tens place: \( 8 - 4 = 4 \).
3. Subtract the hundreds place: \( 2 - 2 = 0 \).

So, \( 297 - 248 = 49 \).
