If the measurements are of like things (eg distances) to find the ratio convert one of them into the units of the other, then the units an be dropped and the ratio simplified; eg: What is the ratio of 2 cm = 1 km? 1 m = 100 cm 1 km = 1000 m = 1000 × 100 cm = 100,000 cm → 2 cm : 1 km = 2 cm : 100,000 cm = 2 : 100,000 = 1 : 50,000 (This is the scale of the OS Landranger maps). If they are different things, then the units cannot be dropped, and the ratio requires them, eg making a brine solution may require 1 g of salt per 100 ml of distilled water the ratio of salt : water = 1 g : 100 ml.
1:4
It is 1.4 cm and 0.6 cm.
It is the same as 2 cm = 3 m or 1 cm = 1.5 m The scale ratio would therefore be 150:1
to my concerns is is 40cm
The equivalent ratio of 204 to 306 is 2 to 3

The ratio of the circumference of a circle with radius 4 cm to its area is 1:2.
1:4
1:4
The ratio is 3:2
It is 1.4 cm and 0.6 cm.
It is the same as 2 cm = 3 m or 1 cm = 1.5 m The scale ratio would therefore be 150:1
It is: 2 cm to 9 cm
If a cell has a length of 1 cm, its surface area would be equal to length X width X number of sides, or 1 cm X 1 cm X 6= 6 cm squared (2). The volume of the cell would be equal to length X width X number of sides or 1 cm X 1 cm X 1 cm = 1 cm to the 3rd power. To obtain the ratio of surface area to volume, divide the surface area by the volume. In this case, the ratio of surface area to volume would be 6:1 or 6/1.
Convert the units of both sides to the same, then remove the units and simplify (if possible by dividing both sides by a common divisor greater than 1). eg The Landranger series map scale of 2 cm equals 1 km: 1 m = 100 cm 1 km = 1,000 m → 1 km = 1,000 x 100 cm = 100,000 cm 2 cm : 1 km → 2 cm : 1 x 100,000 cm → 2 cm : 100,000 cm → 2 : 100,000 → 1 : 50,000
first lets find out the relation between cm and km . the relation is 1 km=100000 cm. 2 cm =0.00002 km . now finding the ratio of 2 cm to 1000 km . 0.00002 : 1000 = 2 : 10 ^ 8 = 1 : 10 ^ 8 /2 .
