Kelly has 4 times as many songs on her music player as lou. tiffany has 6 times as many as songs on her music player as lou. altogether they have 682 songs on their music player how many songs dose kelly have

  248

Step-by-step explanation:

The ratios of the numbers of songs are ...

  kelly : tiffany : lou = 4 : 6 : 1

Then kelly has 4/(4+6+1) = 4/11 of the total number of songs.

  (4/11)(682) = 248

Kelly has 248 songs on her music player.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
