you watch them and see whos in frist so you can write it down
As a percentage ratio they are: 12.5% 37.5% and 50% respectively
24:48. 1:2. 48 and 24 is divisible by 2 and 1 respectively. The ratio is 1:2
It is 640/21 oz and 32/21 oz respectively.
If you mean ratio of 2, 3, 4 and 1 then the angles in degrees are 72, 108, 144 and 36 respectively
The perimeters of two similar polygons have the same ratio as the measure of any pair of corresponding sides. So the ratio of the measure of two corresponding sides of two similar kites with perimeter 21 and 28 respectively, is 21/28 equivalent to 3/4.
As a percentage ratio they are: 12.5% 37.5% and 50% respectively
Gear ratio is the ratio of the rotational speeds of the first and last gears. It reflects the change in mechanical advantage which results from the gears.
100:1 respectively
729:1
343:1
343:1
16/9
It is: 2 to 3 respectively
24:48. 1:2. 48 and 24 is divisible by 2 and 1 respectively. The ratio is 1:2
Because it is the ratio of two speeds (which will have identical units), the units cancel.
A dimensionless quantity is one that has only a number, not a unit, and should therefore be the same in any system of units. This often happens when a quantity is the ratio of two measurements of the same kind. For example, the index of refraction can be considered the ratio of two speeds (the speed of light in a vacuum, and the speed of light in the corresponding substance); if both speeds are expressed in meters/second, when taking the ratio, the units disappear, and only a number without units - a "dimensionless" unit - remains. If you convert the speeds in this example to some other unit, for example kilometers per second, both speeds will be a thousand times less; but the ratio will still be the same.
It is not. Suppose I cycle at 20 km per hour and a car travels at 50 km per hour. So the ratio of the speeds is 20/50 or 2/5. In 4 hours I will travel 80 km while in half an hour the car will travel 25 km. The ratio of the distances is, therefore, 80/25 = 16/5 which is NOT 2/5.
