Multiply 3/7 by 9/10 9/10 .(1 point)

Answer 1

To multiply 3/7 by 9/10, we multiply the numerators together and the denominators together separately.

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

Answer 2

Multiply 4/9 by −3 . Write the answer as a mixed number in simplest form.(1 point)

Answer 3

To multiply 4/9 by -3, we multiply the numerator by -3 and leave the denominator the same.

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

To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 3.

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

Since the numerator is negative, we can write this as a mixed number by dividing the numerator by the denominator:

-4 / 3 = -1 and 1/3

Therefore, the answer is -1 1/3.

Answer 4

Multiply 2/3 by 1 1/4 . Write the answer in simplest form.(1 point)

Answer 5

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

1 1/4 = (4 * 1 + 1) / 4 = 5/4

Now, we can multiply the fractions:

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

To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 2.

(10 / 2) / (12 / 2) = 5 / 6

Therefore, the answer is 5/6.

Answer 6

Answer 7

To multiply 9.6 by 0.2, we can simply multiply the two numbers together:

9.6 * 0.2 = 1.92

Therefore, the answer is 1.92.

Answer 8

Multiply 2.6 by −1.3 .(1 point)

Answer 9

To multiply 2.6 by -1.3, we can simply multiply the two numbers together:

2.6 * -1.3 = -3.38

Therefore, the answer is -3.38.

Answer 10

What is the quotient of −91÷(−13)÷7 ?(1 point)

Answer 11

To find the quotient of -91 ÷ (-13) ÷ 7, we need to perform each division step-by-step, following the order of operations (PEMDAS).

First, let's simplify -91 ÷ (-13):

-91 ÷ (-13) = 7

Now, we can divide 7 by 7:

7 ÷ 7 = 1

Therefore, the quotient of -91 ÷ (-13) ÷ 7 is 1.
