I need some help with the question

Mathematics

vagabundo [1.1K]4 years ago

To solve this you first need to turn your mixed numbers into improper fractions. to do this for 9 \frac{4}{5} you multiply the denominator (5) by the whole number (9) to get 45 and then add that to the numerator (4) to get your new fraction \frac{49}{5}.

You repeat this process with 3\frac{1}{2} to get \frac{7}{2}.

Now that you have two fractions you can multiply by the opposite reciprocal. To do this you flip the second fraction and change the division sign to a multiplication sign like so \frac{49}{5} * \frac{2}{7}

Then, you just multiply the fractions by multiplying the numerators to get 98 and multiplying the denominators to get 35.

Now, to simplify \frac{98}{35} * \frac{2}{7} you first divide both the numerator and denominator by 7 to get \frac{14}{5} * \frac{2}{7}.

Finally, you can take 10 out of the numerator to make 2\frac{4}{5} * \frac{2}{7}

Svetllana [295]

Answer:

The father was either 29 or 28 years old when the author of the question was born.

El padre tenía 29 o 28 años cuando nació el autor de la pregunta.

Step-by-step explanation:

English Translation

My grandmother gave birth to my father, when she was under 20 years old, and I was born when my father was over 25 years old, if my father is now under 45 years old and I was in my fourth year of high school, how old is my father when I was born.

Solution

Assuming that the author of the question is a typical fourth year high school student.

The age of fourth year high school students normally range from 16 to 17.

The father is currently 45 years old, so the age of the father when the author of the question was born is given as

(45 - 16) or (45 - 17)

= 29 or 28 years old.

which satisfies the condition given in the question that the father was more than 25 years old!

Hope this Helps!!!

In Spanish/En español

Asumiendo que el autor de la pregunta es un típico estudiante de secundaria de cuarto año.

La edad de los estudiantes de cuarto año de secundaria normalmente oscila entre 16 y 17.

El padre tiene actualmente 45 años, por lo que la edad del padre cuando nació el autor de la pregunta se da como

(45 - 16) or (45 - 17)

= 29 o 28 años.

que satisface la condición dada en la pregunta de que el padre tenía más de 25 años!

¡¡¡Espero que esto ayude!!!
