Mapel : MatematikaBab : Perbandingan
Diketahui :
Bima = 24 hari
Adit = 8 hari
Ditanyakan :
Jika dikerjakan bersama-sama = ... ?
Penyelesaian :
Jika dikerjakan bersama-sama
= 1 : ( 1/24 + 1/8 )
= 1 : ( 1/24 + 3/24 )
= 1 : 4/24
= 24/24 x 24/4
= 24/4
= 6 hari
Jadi, jika Adit dan Bima bekerja bersama-sama mengecat rumah akan selesai dalam waktu 6 hari
