### Instruction:
 Uwiano wa wavulana na wasichana katika familia ni 5:7. Jumla ya watoto katika familia ni 180. Ikiwa wavulana wamepewa $3900 kugawana, kila mvulana atapokea kiasi gani cha pesa?


### Response:
 Uwiano wa wavulana na wasichana ni 5:7.
Jumla ya watoto ni 180.
Jumla ya wavulana ni 180 * 5/12 = <<180*5/12=75>>75.
Kila mvulana atapokea 3900/75 = <<3900/75=52>>52 dola.
