So you have:
1) Start off by multiplying both sides by x to simplify the problem:
2) Now isolate the x by moving all terms with x onto one side and all other terms onto the other side:
3) Finally, divide by 3 on both sides to find the value of x:
------

or
32%
Step-by-step explanation:
Students must specialize in one style of dance.
Last summer there was 62 dancers.
20 of the 62 specialized in modern dance.
Therefore the probability of a random chosen dancer to be a modern specification is 20/62.
The answer is:
Fraction:
10
---
31
Whole number:
0.32
Percent:
32%
Using the percentile concept, it is found that 10 students scored lower than he did.
<h3>What is the meaning of the percentile of a measure?</h3>
When a measure is in the xth percentile of a data-set, it is greater than x% of the measures and lesser than (100 - x)%.
In this problem, he scored on the 20th percentile, that is, higher than 20% of the 50 students. Then:
0.2 x 50 = 10.
10 students scored lower than he did.
