Contoh 2. Affandi membelanjakan 26% daripada jumlah
simpanannya untuk membeli sebuah kamus. Cari nisbah
65% daripada murid Tingkatan 1 Beta gemar bermain wang yang dibelanjakan kepada jumlah simpanannya.

badminton kepada jumlah murid Tingkatan 1 Beta. ratio of the amount of money spent to his total savings.
65% of Form 1 Beta students like to play badminton. Find the
ratio of the number of students who like to play badminton to the Peratusan wang yang dibelanjakan
total students of Form 1 Beta. Percentage of the amount of money spent
= 26%
Peratusan murid yang gemar bermain badminton 26
Percentage of students who like to play badminton =
100
= 65%
65 Nisbah wang yang dibelanjakan kepada jumlah wang
=
100 simpanan
Ratio of the amount of money spent to the total savings
Nisbah bilangan murid yang gemar bermain badminton = 26 : 100
kepada jumlah murid = 13 : 50
Ratio of the number of students who like to play badminton to the
total students
= 65 : 100
= 13 : 20

Contoh 3. Satu pasukan bola sepak menang 80% daripada
perlawanan yang dimain dan kalah dalam perlawanan
52% daripada murid Tingkatan 1 Cekal terdiri daripada murid

Peratusan murid lelaki
Peratusan menang
Percentage of boys
Percentage of games won
= 52%
= 80%
Peratusan murid perempuan
Peratusan kalah
Percentage of girls
Percentage of games lost
= 100% – 52%
= 100% – 80%
= 48%
= 20%
Nisbah bilangan murid lelaki kepada bilangan murid Nisbah menang kepada kalah
perempuan Ratio of games won to games lost
Ratio of the number of boys to the number of girls
= 80% : 20%
= 52% : 48%
= 80 : 20
= 52 : 48 80 20
52 48 = :
= : 20 20

= 13 : 12 = 4 : 1
