Some girls in a Girl Scout troop are pairing up with some boys in a Boy Scout troop to practice square dancing. Two-thirds of th

Natalka [10]

Answer:

Fraction of the scouts are square dancing is $\frac{19}{30}$ .

Step-by-step explanation:

Each pair is one Girl Scout and one Boy Scout.

So, to the final fraction ( of the pairs) we are going to get 1/2 from the fraction of girls and 1/2 from the fraction of boys.

Girls= $\frac{2}{3} *\frac{1}{2} =\frac{2}{6}$

Boys= $\frac{3}{5} *\frac{1}{2} =\frac{3}{10}$

To get the fraction of the scouts that are square dancing, we have to add the fraction of girls , with the fraction of boys.

= $\frac{2}{6} +\frac{3}{10}$

= $\frac{(2*10) +(6*3)}{6*10} =\\ \frac{20+18}{60}$

= $\frac{38}{60}$

= $\frac{19}{30}$

This means that from 30 scouts , 19 are dancing.
