What is a ratio of two numbers that have different units?
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.
What is the simplified ratio of 80 cm to 2 m?
To simplify the ratio of 80 cm to 2 m, we first convert both measurements to the same unit. Since 1 m is equal to 100 cm, 2 m is equal to 200 cm. The ratio then becomes 80 cm to 200 cm. To simplify this ratio, we divide both numbers by their greatest common factor, which is 40. Therefore, the simplified ratio of 80 cm to 2 m is 2:5.
The areas of 2 rectangles are 15 square cm and 60 square cm what is the ratio of the first to the second?
1:4
What is 2 cm in the ratio of 7 3?
It is 1.4 cm and 0.6 cm.
What is the scale factor for 12 cm equals 18 m?
It is the same as 2 cm = 3 m or 1 cm = 1.5 m The scale ratio would therefore be 150:1
