Question

en un parque hay una zona de columpios y una pista de patinaje que ocupa en total 5 quintos del espacio .si los columpios ocupan 2 septimos del parque . que fraccion del parque ocupa la pista de patinaje​

Answer 1

The rink occupies 69% of the whole park, approximately, which is equivalent to 280/408.

Explanation:

To solve this problem, we need to find the number which express the whole park.

Notice that the park is divided in two sections, one occupies 5/8 of the total, and the other occupies 2/7 of the total. So, the sum would be

`(5)/(8)+(2)/(7)=(35+16)/(56) =(51)/(56)`

Now we have the total space there, we need to divide 5/8 by 51/56, so

`(5)/(8) / (51)/(56)=(5)/(8) * (56)/(51)=(280)/(408) \approx 0.69`

Therefore, the rink occupies 69% of the whole park, approximately, which is equivalent to 280/408.
