Question

Tolong banatuin jawab soal diatas yamg no.1-5 pakai cara..

Answer 1

1) = 100% - 55% - 15% = 100/100 - 55/100 - 15/100
    = 45/100 - 15/100 = 30/100 = 3/10
     
2) = 640 x 3/8 + 240 = 1.920/8 + 240 = 240 + 240 = 480
    yang belum terisi
    = 480/640 = 0,375

3) = soalnya terpotong

4) = 0,9 + 1 1/5 + 3/8 = 9/10 + 6/5 + 3/8 = 36/40 + 48/40 + 15/40
    = 99/40 = 2 19/40 = 2,475 kg

5) gak jelas juga soaqlnya kepotong...

moga membantu...
