because 3 parts are shaded ok 8 parts are not shaded
Answer:
1. 1 : 4
2. 3 : 8
3. 8 : 5
Step-by-step explanation:
1.
1 minute = 60 seconds
1 / 3 of a minute = 60 / 3 = 20 seconds
The ratio of 5 seconds to 1 / 3 of a minute,
= 5 seconds : 1 / 3 of a minute
= 5 : 20
= 5 / 20
= 1 / 4
= 1 : 4
Therefore, the ratio of 5 seconds to 1 / 3 of a minute is 1 : 4.
2.
Total parts ( whole ) = 8
Shaded parts ( shaded portion ) = 3
The ratio of shaded portion to the whole,
= shaded portion : whole
= 3 : 8
Therefore, the ratio of shaded portion to the whole is 3 : 8.
3.
Total students = 40
Total boys = 15
Total girls = Total students - Total boys
= 40 - 15
Total girls = 25
The ratio of total students to total girls,
= Total students : Total girls
= 40 : 25
= 40 / 25
= 8 / 5
= 8 : 5
Therefore, the ratio of total students to total girls is 8 : 5.
