Answer:

3. \frac{1}{12}

4. \frac{22}{3}

5. \frac{5}{42}

8. \frac{8}{63}

9. -\frac{7}{54}

10. -\frac{3}{16}

Step-by-step explanation:

3.

\frac{-6}{8} *\frac{1}{-9} =\frac{-6}{-72}

ahora simplifica, un numero negativo dividido por otro numero negativo se convierte en positivo. Los dos nu$meros se pueden simplificar por 6

\frac{1}{12}

4.

\frac{11}{3}*\frac{4}{2} =\frac{44}{6}

ahora simplifica, los dos nu$meros se pueden simplificar por 2

\frac{22}{3}

5.

\frac{5}{-3}*\frac{-2}{7}* \frac{1}{4} =\frac{-10}{-84}

ahora simplifica, un numero negativo dividido por otro numero negativo se convierte en positivo. Los dos nu$meros se pueden simplificar por 2

\frac{5}{42}

8.

\frac{20}{-5}*\frac{1}{-9}* \frac{-2}{-7} =\frac{-40}{-315}

ahora simplifica, un numero multiplicado por otro negativo se convierte en positivo. Un numero negativo dividido por otro numero negativo se convierte en positivo. Los dos nu$meros se pueden simplificar por 5

\frac{8}{63}

9.

\frac{2}{3}*\frac{-7}{-9}* \frac{-1}{4} =\frac{14}{-108}

ahora simplifica, un numero multiplicado por otro negativo se convierte en positivo. Un numero positivo dividido por un numero negativo se convierte en negativo. Los dos nu$meros se pueden simplificar por 2

-\frac{7}{54}

10.

\frac{9}{-12}*\frac{-4}{16} =\frac{-36}{-192}

ahora simplifica, un numero negativo dividido por otro numero negativo se convierte en positivo. Los dos nu$meros se pueden simplificar por 12

-\frac{3}{16}

Espero y te ayude esto! (:

A fair dice is rolled 3 times in a row. The outcomes are shown below.
maks197457 [2]

Answer:

1/3

Step-by-step explanation:

I think this is 1/3 because it is a ratio of successful outcomes to total number of outcomes..

Ex. Rolling a 6 sided dice.. you roll a 5...  it would be 1/6.

Hope that makes sense.

Hunter is 35 years older than Andrew. After 5 years Hunter will be twice Andrew's age. Find the present age of both.
Anettt [7]

Answer:

Andrew is 30 years old. Hunter is 65 years old.

Step-by-step explanation:

we can set up 2 equations:

h = 35 + a

h+5 = 2(a+5)

Solve for h in the second equation.

h + 5 = 2a + 10; h = 2a + 5

now set the 2 equations = to each other

2a + 5 = 35 + a

solve for a by combining like terms

a + 5 = 35

a = 30

so Andrew is 30 and Hunter is 35 + 30 = 65.

Sp in 5 years Andrew is 35 and Hunter is 70 (twice A's age)

Pls help me with this math problem​
DENIUS [597]

Answer:

The four rational numbers between -\frac{1}{2} and \frac{1}{2} can be:

  • -\frac{1}{3}
  • -\frac{1}{4}
  • \frac{1}{5}
  • \frac{1}{7}

Step-by-step explanation:

The definition of rational numbers is usually a number of the type a/b where b is different from zero, therefore, to choose the numbers that are between -1/2 (= -0.5) and 1/2 (= 0.5) <u><em>it is enough with choose fractional numbers whose dividend is 1 and its divisor is any number greater than 2, either negative or positive,</em></u> in the answer we choose options such as 1/7 or -1/3, but following the guide I give you, you could choose numbers like 1/16, -1/9 or 1/40 if you wish, always respecting the guidelines given for the dividend and the divisor.
