How do you turn a ratio into a decimal?
To turn a ratio into a decimal, divide the first number of the ratio by the second number. For example, if the ratio is 3:4, you would calculate 3 ÷ 4, which equals 0.75. This decimal represents the same relationship as the original ratio.
How do you calculate radius to volume ratio of a sphere?
To calculate the radius to volume ratio of a sphere, first determine the volume using the formula ( V = \frac{4}{3} \pi r^3 ), where ( r ) is the radius. Then, the radius to volume ratio is given by ( \frac{r}{V} = \frac{r}{\frac{4}{3} \pi r^3} ). Simplifying this expression results in the ratio ( \frac{3}{4\pi r^2} ). Thus, the radius to volume ratio decreases as the radius increases.
How can you write a ratio as a decimal?
To write a ratio as a decimal, divide the first number of the ratio by the second number. For example, if the ratio is 3:4, you would calculate 3 ÷ 4, which equals 0.75. This decimal representation can also help in comparing ratios or converting them into percentages if needed.
What percentage is 4 to 3 to 2 ratio?
To find the percentage of each part in the ratio 4:3:2, first add the parts together: 4 + 3 + 2 = 9. Then, calculate the percentage for each part by dividing each part by the total and multiplying by 100. Thus, 4 is approximately 44.44%, 3 is about 33.33%, and 2 is around 22.22% of the total ratio.
How do you express ratio?
You express ratio as a fraction. For instance, the ratio of 3 to 4 is 3/4, or .75
What is the ratio of a number?
There is no such thing as the ratio of a number. You need two numbers to calculate a ratio. A ratio is the same as a quotient. For example, the ratio of 4 to 2 is the same as 4 divided by 2.
What is the ratio for the volumes of two similar spheres given that the ratio of their radii is 3 4?
ratio of volumes is the cube of the ratio of lengths radii (lengths) in ratio 3 : 4 → volume in ratio 3³ : 4³ = 27 : 64
How do you divide a ratio into a number?
To divide a ratio by a number, you divide both terms of the ratio by that number. For instance, if you have a ratio of 4:6 and want to divide it by 2, you would calculate (4 ÷ 2) and (6 ÷ 2), resulting in a new ratio of 2:3. This maintains the proportional relationship of the original ratio while scaling it down.
What is the ratio from 3 to 4?
It is 3/4.
Is it possible to have a triangle whose angle measures are in the ratio 3 to 4 to 5 and whose side lengths are the same ratio?
No. If the angles are in the ratio 3:4:5, the sides will be in the ratio sin(3):sin(4):sin(5) - NOT in the ratio 3:4:5.
How do you convert a ratio to decimal?
Convert the ratio to fraction first, then convert the fraction to decimal. Example: ratio = 3 : 4 3 : 4 = 3/4 = 0.75
How would you calculate the surface area to volume to ratio?
surface area to volume ratio can be solved by solving the surface are of something and the volume of something then putting them togetherEXAMPLE: if it is a cube with 4 cm on each side it would be 6(4)^2 = 6(16)=96cm and volume would be 4^3= 64 so ratio would be 96:64 which can be simplified 3:2 or 3 to 2
