2/5 of the girls in the school signed up to play softball. an equal number of girls signed up to play pitcher , in the field, and outfield. what fraction of the girls in the school signed up to play outfield?

2/15

Step-by-step explanation:

1/3 of 2/5 signed up for outfield, so we have to find out what 1/3 of 2/5 is. For that, we multiply 2/5 by 1/3.

2/5 * 1/3 = 2/15

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
