It is: 4 to 3
To find the ratio of 20 and 15, you divide 20 by 15. The ratio is typically expressed in simplest form, so you would divide both numbers by their greatest common divisor, which in this case is 5. Therefore, the ratio of 20 to 15 is 4:3.
20 cm x 15 cm = 300 cm2
The length is 20 cm.
3/4
Let the breadth be x and the length be x+20 So: 2*(x+x+20) = 100 => 4x+40 = 100 => 4x = 100-40 => 4x = 60 => x = 15 The dimensions are: length = 35 cm and breadth = 15 cm Check for perimeter: 2*(35+15) = 100 cm
15/20=3/4
The ratio is 15:1Here's why:1 cm = 10 mm, so 120 cm = 1200 mm1200/80 = 15/1
The ratio is 3 to 4
To find the ratio of 20 and 15, you divide 20 by 15. The ratio is typically expressed in simplest form, so you would divide both numbers by their greatest common divisor, which in this case is 5. Therefore, the ratio of 20 to 15 is 4:3.
1:4
20 cm x 15 cm = 300 cm2
20 cm is 15 pence
The ratio is: 3 to 4
It is 15/100 = 3/20.
The ratio of students to teachers is 300:15. This can be simplified by dividing both numbers by 15, resulting in a simplified ratio of 20:1. This means there are 20 students for every teacher.
15:100 = 3:20
20 cm times 15 cm = 300 square cm
