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 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.
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

Find the x value for point C such that AC and BC form a 23 ratio.?
It is (2*Ax + 3*Bx)/5 where Ax and Bx are the x coordinates of A and B.
How do you tell if the ratios are equivanlent?
The simplest way: Ratio a : b equals ratio c : d if (and only if) a*d = b*c
How do you write a ratio of two fractions?
The ratio of (a/b) and (c/d) is (a/b)/(c/d) = (a/b)*(d/c) = ad/bc So, the method is to multiply the first fraction by the reciprocal of the second.
