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.
the ratio of A to B is 2:3 and the ratio of B to C is 4:5. what is the ratio of A to C?
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.
What is B plus B plus B plus C plus C plus C?
It is impossible to give any decimal/numeric value if we are not given the values of at least one variable, so the answer is B + B + B + C + C + C.
The incomes of A B and C are in the ratio 7.9.12 and their expenses are in the ratio 8.9.15 If A saves 1by4 -fraction- of his income how would you find the ratio of their savings?
the ratio of the savings of A B and C would be 56, 99, 69
What are Ratios that have the same value and simplified ratio?
Two ratios, a/b and c/d have the same value is a*d = b*c. A ratio, a/b, is said to be simplified if a and b are co-prime.
In the given ratio b and c are mean values?
true
What is the definition of the golden ratio?
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.
How do you solve ratio questions where total is given with possible ratios?
To solve ratio questions where the total is given, first, express the ratio in terms of a common variable. For example, if the ratio is A:B and the total is T, you can write A = kx and B = ky, where k is a constant and x and y represent the parts of the ratio. Then, set up the equation ( k(x + y) = T ) and solve for k. Finally, use k to find the individual values of A and B by substituting back into the expressions for A and B.
What is the ratio of mass a to mass b?
To determine the ratio of mass a to mass b, you simply divide mass a by mass b. This can be expressed as a:b, which is equal to a/mass b. If you have the specific values for mass a and mass b, you can calculate the numerical ratio accordingly.
How do you do ratios?
you write it like a fraction. modelo: 4/5
What are the uses of ratio's?
With probability ratios the value you get to describe the strength of the relationship when you compare (A given B) to (A given not B) is not the same as what you get when you compare (not A given B) to (not A given not B). This is, IMHO, a big problem. There is no such problem with odds ratios.

What is the ratio of A girls to B boys in simplest form?
To determine the ratio of A girls to B boys in simplest form, divide both A and B by their greatest common divisor (GCD). The resulting values will give you the simplest ratio of girls to boys. For example, if A is 8 and B is 12, the GCD is 4, so the ratio simplifies to 2:3.
Which table shows a proportional relationship between a and b?
To determine if a table shows a proportional relationship between ( a ) and ( b ), you need to check if the ratio ( \frac{b}{a} ) remains constant for all pairs of values. If the ratio is the same across the entire table, then ( a ) and ( b ) are proportional. Additionally, if the values of ( b ) can be expressed as a constant multiple of ( a ), that also indicates a proportional relationship.
What are the values of a and b given that y plus 4x equals 11 is the perpendicular bisector equation of the line joining a 2 to 6 b?
Their values work out as: a = -2 and b = 4
Is a plus b divisible by c?
Sometimes. It depends on the values given to the variables.
What is the galden ratio?
Consider two values a and b. They are said to be in the golden ratio when b/a = (a + b)/b The mathematical term for this ratio is "tau" or "phi" and it equals 1.618. It can be calculated if we put a = 1, then b = (b+1)/b ie b2 = b + 1 or b2 - b - 1 = 0. Using the quadratic formula gives b = (1 + sqrt5)/2 ie (1 + 2.236)/2 = 3.236/2 = 1.618
