wat is the ratio of a and b

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.

This deals with ratios and proportions.

A : B = 2 : 3

B : C = 4 : 5.

Now, to find A : B : C, we need to make the value of B equal in A : B ratio and B : C ratio.

Here, Value of B in A : B ratio is 3; and B : C ratio is 4.

LCM of 3 and 4 is 12. Therefore, we multiply 4 to the first ratio and 3 to the second ratio.

A : B = 2 × 4 : 3 × 4

A : B = 8 : 12

Also,

B : C = 4 × 3 : 5 × 3

B : C = 12 : 15

Now, we can combine A : B and B : C.

A : B : C = 8 : 12 : 15.

Given two quantities, when the ratio of the larger quantity to the smaller one is equal to the ratio of the sum of the quantities to the larger one, then the ratio is said to be the golden (or divine) ratio. Said another way, given two quantities (a and b), a is to b as a plus b is to a. Expressed symbolically: a : b :: a + b : a Expressed algebraically, it looks like this: a/b = (a + b)/a, where a > b. The golden ratio is approximately 1.6180339887.

Yes. If each of a and b is a number and b is not zero, the ratio of a to b, often written as a:b, = a/b.
