Which ratio forms a proportion with 16/20

Answers

Answer 1
Answer:

Answer:

4/5 forms a proportion with 16/20.

Step-by-step explanation:

We are given an rational number as 16/20.

we have to find another rational number which is equivalent to it.

as both 16 and 20 are multiple of 4 we could also represent the ratio 16/20 as:

(16)/(20)=(4 * 4)/(4*5)

we cancel 4 on both the numerator and denominator to get (4)/(5).

Hence,  the ratio (4)/(5) is proportion with (16)/(20).
Answer 2
Answer: 4/5 is equivalent to the fraction 16/20

Given:

The table representing the relative frequencies of different sports in different grades among the students.

                           Swimming      Running    Volleyball                   Row totals

Grade 8                        0.14           0.18         0.22                          0.54

Grade 9                        0.17           0.24        0.05                          0.46

Column totals              0.31           0.42        0.27                             1

Relative frequency givesthe ratio of the number of quantities of a particular kind and the total number of quantities.

\textrm{Relative frequency}=\frac{\textrm{Number of students in a particular sport}}{\textrm{Total students}}

From the above table, we can conclude the following points:

Grade 8:

14% liked swimming, 18% liked running and 22% liked volleyball. So, a total of 54% students liked playing sports.

Grade 9:

17% liked swimming, 24% liked running and 5% liked volleyball. So, a total of 46% students liked playing sports.

Combining students of grade 8 and 9:

31% liked swimming, 42% liked running and 27% liked volleyball.

From all the options available, we observe that, third option is only correct.

In Grade 8, 22% of students liked volleyball.
