Answer 1

Answer:

Commutative property of multiplication: Changing the order of factors does not change the product. For example, 4 \times 3 = 3 \times 44×3=3×44, times, 3, equals, 3, times, 4.

Associative property of multiplication: Changing the grouping of factors does not change the product. For example, (2 \times 3) \times 4 = 2 \times (3 \times 4)(2×3)×4=2×(3×4)left parenthesis, 2, times, 3, right parenthesis, times, 4, equals, 2, times, left parenthesis, 3, times, 4, right parenthesis.

Identity property of multiplication: The product of 111 and any number is that number. For example, 7 \times 1 = 77×1=77, times, 1, equals, 7.

Commutative property of multiplication

The commutative property of multiplication says that changing the order of factors does not change the product. Here's an example:

4 \times 3 = 3 \times 44×3=3×44, times, 3, equals, 3, times, 4

Notice how both products are 121212 even though the ordering is reversed.

Here's another example with more factors:

1 \times 2 \times 3 \times 4 = 4 \times 3 \times 2 \times 11×2×3×4=4×3×2×11, times, 2, times, 3, times, 4, equals, 4, times, 3, times, 2, times, 1

Notice that both products are 242424.

Answer 2

Answer:

1) 93/12

2) 32/5

3) -61/240

4) 1/4

Step-by-step explanation:

(1). 6+{4/3+(3/4-1/3)}

6+{4/3+(9-4/12)}

6+{4/3+5/12}

6+(16+5/12)

6+21/12

72+21/12

93/12. (ans)

2). 8-{3/2+(3/5-1/2)}

8-{3/2+(6-5/10)}

8-{3/2+1/10}

8-(15+1/10)

8-16/10

80-16/10

64/10

32/5. (ans)

3). 1/4(1/4+1/3)-2/5

1/4(3+4/12)-2/5

1/4×7/12-2/5

7/48-2/5

35-96/240

-61/240. (ans)

4). 11/4-[25/8÷5-(14/3-11/12)]

11/4-[25/8÷5-(56-11/12)]

11/4-[25/8÷5-45/12]

11/4-[25/8÷15/12]

11/4-[25/8×12/15]

11/4-5/2

11-10/4

1/4. (ans)
