%Matematika
= 100% - 10% - 25% - 15% - 25%
= 25%
menentukan jumlah siswa yang gemar matematika (dimisalkan x)
x = 25%/100% × jumlah siswa
x = 25/100 × 40
x = ¼ × 40
x = 10 siswa
Penjelasan dengan langkah-langkah:
gemar pelajaran matematika
persentase nya
= 100% - (10+25+15+25)
= 100% - 75%
banyak nya
= 25/100 × 40
= 1000/100
= 10/1
= 10 siswa
