In the dancing performance, there are 28 men.
Given info;
As the ratio of men to women is 7 : 8, if there are 7x men, there are 8x women.
But we have 64 female performers in the dance recital.
Hence, 8x = 64
Now multiplying both sides by 1/8, we have
⇒ 8x * 1/8 = 32 * 1/8
x = 4
Hence there are 7 × 4 = 28 men in the dance recital.
