It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
A dance school has 63 ballet dancers. If 42% of the total number of dancers in the school are ballet dancers.
Let x be the total number of dancers in the school.
42% of x = 63
(42/100)x = 63
0.42x = 63
x = 63/0.42
x = 150
Thus, the total number of dancers in the school is 150 if a dance school has 63 ballet dancers. If 42% of the total number of dancers in the school are ballet dancers option (B) 150 is correct.
