Two-fifths of the girls signed up to play softball. An equal number of girls signed up to play pitcher, infield, and outfield. W
Natali [406]
Okay so lets look at this.

So we have 5/5 girls.

2/5 of them are playing softball.  An equal number of girls signed up to play pitcher, infield, and outfield.  This means that each one is 1/3.

So out of 2/5 of the girls, there is 1/3 of the 2/5 that signed up to play outfield.

The answer can be solved with multiplication of fractions.

2/5 * 1/3 is 2/15.  So 2/15 of the girls in the school signed up to play outfield.

Answer: 2/15 or 0.133
