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 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.
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 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 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
What is the ratio of a to b?
wat is the ratio of a and b
How do you find a number of somthing from a ratio?
If you are given a ratio, r , then r = x/y ( If the ratio is given as x : y, or x to y think of it as x/y . Also remember the r% means r/100 if the ratio is given as a percentage. ) Therefore by basic algebra, x = ry and y = x/r . So you find either number from the other, given the ration. Example The ratio of boys to girls in a physics class is 8 to 2. There are 4 girls. How many boys are in the class? b/g = 8/2 so b/4 = 8/2 and b = 4(8/2) = 16 boys in the class.
What are two different size squares that the ratio of their perimeters is the same as the ratio of their areas?
Assume square A with side a; square B with side b. Perimeter of A is 4a; area of A is a2. Perimeter of B is 4b; area of B is b2. Given the ratio of the perimeters equals the ratio of the areas, then 4a/4b = a2/b2; a/b = a2/b2 By cross-multiplication we get: ab2 = a2b Dividing both sides by ab we get: b = a This tells us that squares whose ratio of their perimeters equals the ratio of their areas have equal-length sides. (Side a of Square A = side b of Square B.) This appears to show, if not prove, that there are not two different-size squares meeting the condition.
