Use properties of operations and rules for multiplying signed numbers to multiply

Question

A.-6/50

B. 3/5

C. -6/5

D. -3/25

Answer 1

To multiply signed numbers, we can follow the rules:

1. If the numbers have the same sign (both positive or both negative), the product is positive.
2. If the numbers have different signs (one positive and one negative), the product is negative.

Now let's multiply:

A. -6/50 * 3/5 = (-6 * 3) / (50 * 5) = -18/250 = -9/125

B. 3/5 * 3/5 = (3 * 3) / (5 * 5) = 9/25

C. -6/5 * -6/5 = (-6 * -6) / (5 * 5) = 36/25

D. -3/25 * -6/50 = (-3 * -6) / (25 * 50) = 18/125

Answer 2

Use properties of operations and rules for multiplying signed numbers to multiply -2/5 by 3/10

A.-6/50

B. 3/5

C. -6/5

D. -3/25

Answer 3

To multiply -2/5 by 3/10, we can simply multiply the numerators and denominators:

(-2/5) * (3/10) = (-2 * 3) / (5 * 10) = -6/50

So the answer is A. -6/50.

Answer 4

Multiply 4 by -5/8 write the answer as a mixed number in simplest form

A. -2 4/8

B.-5/2

C. -2 1/2

D. -10

Answer 5

To multiply 4 by -5/8, we multiply the whole number by the fraction:

4 * (-5/8) = -20/8

To simplify the fraction, we can reduce the numerator and denominator by dividing both by their greatest common divisor, which is 4:

-20/8 ÷ 4/4 = -5/2

So the answer is B. -5/2.

Answer 6

Multiply 6.5 by 0.3 write the answer as a decimal

A. 0.195

B. 1.86

C. 1.95

D. 19.5

Answer 7

To multiply 6.5 by 0.3, we multiply the two numbers:

6.5 * 0.3 = 1.95

So the answer is C. 1.95.

Answer 8

Multiply-19.3 by 6

Answer 9

To multiply -19.3 by 6, we multiply the two numbers:

-19.3 * 6 = -115.8

So the answer is -115.8.

Answer 10

Multiply -2 1/2 by -1 3/5 write the answer as a decimal

A. 4

B. -4

C. 2.86

D. -4.1

Answer 11

To multiply -2 1/2 by -1 3/5, we first convert the mixed numbers to improper fractions:

-2 1/2 = -5/2
-1 3/5 = -8/5

Next, we multiply the fractions:

(-5/2) * (-8/5) = (5 * 8) / (2 * 5) = 40/10 = 4

So the answer is A. 4.

Answer 12

Multiply 3/7 by 9/10

Answer 13

To multiply fractions, we simply multiply the numerators together and the denominators together:

(3/7) * (9/10) = (3 * 9) / (7 * 10) = 27/70

So the answer is 27/70.

Answer 14

Multiply 4/9 by -3 write the and as a mixed number

Answer 15

To multiply 4/9 by -3, we simply multiply the numerator of the fraction by the integer:

(4/9) * -3 = -12/9

Now, let's simplify this fraction. We divide both the numerator and the denominator by their greatest common divisor, which is 3:

-12/9 ÷ 3/3 = -4/3

The result is -4/3. To write this as a mixed number, we divide the numerator by the denominator:

-4 ÷ 3 = -1 remainder 1

Therefore, the mixed number is -1 1/3.

Answer 16

Multiply 2/3 by 1 1/4

Answer 17

To multiply 2/3 by 1 1/4, we first convert the mixed number to an improper fraction:

1 1/4 = 5/4

Next, we multiply the fractions:

(2/3) * (5/4) = (2 * 5) / (3 * 4) = 10/12

Now, let's simplify this fraction. We divide both the numerator and the denominator by their greatest common divisor, which is 2:

10/12 ÷ 2/2 = 5/6

The result is 5/6.
