Use the properties of operations and rules for multiplying and dividing to solve: (−2)×(15)÷(23)×(−56)÷(34)

Answer 1

To solve this expression, we'll use the properties of operations and rules for multiplying and dividing.

First, let's combine the multiplication and division in the expression from left to right:

−2 × 15 ÷ 23 × −56 ÷ 34

Multiply the first two numbers:

= −30 ÷ 23 × −56 ÷ 34

Divide the result by 23:

= (−30 ÷ 23) × −56 ÷ 34

To simplify, we can reduce the fractions before proceeding further.

−30 ÷ 23 can be written as a fraction:
= (-30 / 1) ÷ (23 / 1)

Now we can apply the rule for dividing fractions:
= (-30 / 1) × (1 / 23)
= -30 / 23

Substitute the value of -30 / 23 back into the expression:

= (-30 / 23) × −56 ÷ 34

Now multiply the two numbers:

= (−30 / 23) × (−56 / 34)

Again, we'll apply the rule for dividing fractions:

= (-30 × -56) / (23 × 34)
= 1680 / 782

This fraction cannot be simplified further. Thus, the result is:

= 840 / 391

Answer 5

I apologize for the incorrect response.

Let's go through the expression again.

(-2) × (15) ÷ (23) × (-56) ÷ (34)

We'll proceed step by step.

First, let's perform the multiplication:

(-2) × (15) = -30

Next, let's perform the divisions from left to right:

-30 ÷ 23 × -56 ÷ 34

-30 ÷ 23 can be written as a fraction:
= (-30 / 1) ÷ (23 / 1)

Now we can apply the rule for dividing fractions:
= (-30 / 1) ÷ (23 / 1)
= (-30 / 1) × (1 / 23)
= -30 / 23

Substitute the value of -30 / 23 back into the expression:

= (-30 / 23) × -56 ÷ 34

Let's perform the next division:

-56 ÷ 34 can be written as a fraction:
= (-56 / 1) ÷ (34 / 1)

Applying the rule for dividing fractions:
= (-56 / 1) ÷ (34 / 1)
= (-56 / 1) × (1 / 34)
= -56 / 34
= -28 / 17

Now we substitute the value of -28 / 17 back into the expression:

= (-30 / 23) × (-28 / 17)

To multiply fractions, we multiply the numerators and denominators:
= (-30 * -28) / (23 * 17)
= 840 / 391

So the answer is 840/391.

Answer 7

I apologize for the previous incorrect response.

Let's solve the expression step by step using the properties of operations and rules for multiplying and dividing:

(-2) × (15) ÷ (23) × (-56) ÷ (34)

First, let's start with the multiplication:
(-2) × (15) = -30

Next, let's perform the divisions from left to right:

-30 ÷ 23 × -56 ÷ 34

To divide, we can write the expressions as fractions:

= (-30 / 1) ÷ (23 / 1) × (-56 / 1) ÷ (34 / 1)

Now let's apply the rule for dividing fractions:

= (-30 / 1) × (1 / 23) × (-56 / 1) × (1 / 34)

We can simplify the expression further:

= (-30 * 1 * -56 * 1) / (1 * 23 * 1 * 34)

= 1680 / (782)

Now let's simplify this fraction, if possible:

= 840 / 391

The expression (-2) × (15) ÷ (23) × (-56) ÷ (34) simplifies to 840/391.

Answer 8

Oi wrong mate

Answer 9

I apologize for the confusion. Let's go through the expression again:

(-2) × (15) ÷ (23) × (-56) ÷ (34)

First, let's perform the multiplication:

(-2) × (15) = -30

Next, let's perform the divisions from left to right:

-30 ÷ 23 × -56 ÷ 34

To divide, we can write the expressions as fractions:

= (-30 / 1) ÷ (23 / 1) × (-56 / 1) ÷ (34 / 1)

Now let's apply the rule for dividing fractions:

= (-30 / 1) × (1 / 23) × (-56 / 1) × (1 / 34)

Now let's simplify the fractions individually:

-30 / 1 = -30
1 / 23 = 1/23
-56 / 1 = -56
1 / 34 = 1/34

Now let's multiply the fractions together:

(-30) × (1/23) × (-56) × (1/34)

To multiply fractions, we multiply the numerators and denominators:

=(-30 × -56) / (23 × 34)

= 1680 / 782

This fraction, 1680/782, cannot be simplified further.

So the answer to the expression (-2) × (15) ÷ (23) × (-56) ÷ (34) is 1680/782.

Answer 10

Use the properties of operations and rules for multiplying and dividing to solve: (9)÷(54)×(79)×(−5)÷(72)

Answer 11

To solve this expression, we'll use the properties of operations and rules for multiplying and dividing.

First, let's perform the divisions from left to right:

(9) ÷ (54) × (79) × (-5) ÷ (72)

To divide, we can write the expressions as fractions:

= (9 / 1) ÷ (54 / 1) × (79 / 1) × (-5 / 1) ÷ (72 / 1)

Now let's apply the rule for dividing fractions:
= (9 / 1) × (1 / 54) × (79 / 1) × (-5 / 1) × (1 / 72)

Now let's simplify the fractions individually:

9 / 1 = 9
1 / 54 = 1/54
79 / 1 = 79
-5 / 1 = -5
1 / 72 = 1/72

Now let's multiply the fractions together:

9 × (1/54) × 79 × (-5) × (1/72)

To multiply fractions, we multiply the numerators and denominators:

= (9 × 1 × 79 × -5 × 1) / (54 × 1 × 1 × 72)

= - 2835 / 3888

So the answer to the expression (9) ÷ (54) × (79) × (-5) ÷ (72) is -2835/3888.
