There are 32 female performers in a dance recital. The ratio of men to women is 3:8. How many men are in the dance recital?
3:8
x4
12:32
The answer is 12 men.
Since the ratio is 3 men to 8 women, and there Are 32 WOMEN, WE NEED TO MULTIPLY BOTH SIDES OF THE RATIO BY 4 FOR OUR RATIO TO BE EQUAL TO OUR OLD RATIO. 3X4=12 AND 8X4=32. THIS RATIO IS TELLING US THAT IF THERE ARE 32 WOMEN, THERE WILL BE 12 MEN.
THERE ARE 12 MEN IN THE DANCE RECITAL.
Let
x------> number of men in the dance recital
y------> number of women in the dance recital
we know that
\(\frac{x}{y} =\frac{3}{8}\) -------> equation \(1\)
\(y=32\) -------> equation \(2\)
Substitute equation \(2\) in equation \(1\)
\(\frac{x}{32} =\frac{3}{8} \\\\ x=\frac{32*3}{8}\)
\(x=12\ men\)
therefore
the answer is
There are \(12\ men\) in the dance recital
