di suatu kelas, perbandingan banyak anak perempuan dan laki-laki adalah 4:5. jika empat anak laki-laki keluar, maka perbandingannya menjadi 1:1. Berapa jumlah anak perempuan di kelas tersebut?
if four boys went out and the ratio changed to 1:1 that's mean there are 4 person in every 1/4 people there. that's mean we can multiply 4 with 4 which is it's equal to 16.

there are 16 girls
