What is the ratio for the volumes of two similar pyramids given that the ratio of their edge lengths is 5 to 7?
The ratio is 57 cubed. This answer does not depend on the fact that you are comparing two similar pyramids; it works the same for two cubes, two spheres, etc. - in general, for any two similar 3D objects.
What number is the golden ratio?
The golden ratio, or golden mean, or phi, is about 1.618033989. The golden ratio is the ratio of two quantities such that the ratio of the sum to the larger is the same as the ratio of the larger to the smaller. If the two quantities are a and b, their ratio is golden if a > b and (a+b)/a = a/b. This ratio is known as phi, with a value of about 1.618033989. Exactly, the ratio is (1 + square root(5))/2.
How do you determine the ratio between two sets of gears?
The ratio is the same as the ratio between the number of teeth.
What is one third divided by two and one third?
One third divided by two and one third = 1/7
Can ratios be irrational?
Yes. But if you have a ratio of two integers, the ratio will be rational by definition.
Is two third equivalent ratio to nine fifteenth?
No.
What is the difference between ratio and a fraction?
A ratio composes two (usually, but can be more) quantities of a whole.A ratio would be set up as 2:3:5 where the first is 40% of the third, and the second is 60% of the third. That would be a basic ratio for something like cement, where you need x bags of one thing to y bags of another and z litres of water.A fraction is a certain type of ratio that compares exactly two quantities that have a part-to-whole relationship.thenumeratorindicates the part and the denominator indicates the whole.1/3 Would indicate a third, which if in a ratio's term would be 1:2 as it'd be 1 part of something to 2 of another.
What does the golden ratio means?
In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities.
Is negative one third an irrational number?
No. A rational number is any number whose magnitude is the ratio of whole numbers.The magnitude of (one third) is the ratio ( 1 / 3 ).
What information do you not have when you simplify a ratio?
Information about the original magnitudes.Also, the signs of the two numbers (you get a positive ratio from two negatives or two positives, a negative ratio from one of each).Information about the original magnitudes.Also, the signs of the two numbers (you get a positive ratio from two negatives or two positives, a negative ratio from one of each).Information about the original magnitudes.Also, the signs of the two numbers (you get a positive ratio from two negatives or two positives, a negative ratio from one of each).Information about the original magnitudes.Also, the signs of the two numbers (you get a positive ratio from two negatives or two positives, a negative ratio from one of each).

How do you validate that fractions are equivalent?
The ratio of the two numerators is the same as the ratio of the two denominators.
SIMPLE explanation of the golden ratio?
Two quantities are in a Golden Ratio if the ratio of the bigger quantity to the smaller quantity is the same as the ratio of the sum of the two quantities to the bigger quantity. In algebraic form, if the two quantities are x and y, and x is the bigger of the two, then they are in the Golden Ratio if x/y = (x+y)/x and that ratio is the Golden Ratio. which equals (1 + √5)/2.
What is the ratio of Two triangles that are similar and have a ratio of similarity of 310 what is the ratio of their areas?
If the ratio of similarity is 310, then the ratio of their area is 96100.
What is a ratio that compares two numbers?
The ratio that compares two numbers is a FRACTION. For example, the ratio of 3:5 can be written as 3/5.
What is two numbers that can be written as a ratio?
1:2 is a ratio
