48 - 10 1/2 - 11,5 - 7 1/4 + 25 = #pakecaraya makasih

48 -10 1/2 - 11,5 - 7 1/4 + 25
= 48/1 - 21/2 - 115/10 - 29/4 + 25/1 (ubah ke pecahan biasa)
= 960/20 - 210/20 - 230/20 - 145/20 + 500/20 (samakan penyebut)
=(960+500)/20 - (210+230+145)/20 (dikelompokkan)
= 1460/20 - 585/20
=875/20 = 175/4

jika bermanfaat jadikan jawaban terbaik ya :)
