Given that X : 3 : (9/2) = (15/4) : (9/2) : Y
find the value of X and of Y.
help me to solve this question and thank you so much ;)
 
Hello, and welcome to FMH!

If we are told:

\(\displaystyle a:b:c=d:e:f\)

Then we know:

\(\displaystyle \displaystyle k=\frac{a}{d}=\frac{b}{e}=\frac{c}{f}\)

Can you use this to obtain, from the given information, an equation involving only \(\displaystyle X\) and another equation involving only \(\displaystyle Y\)?

Thank you so much. Now i can solve the problem
the value of X is 5/2 and the value of Y is 27/4
Thanks :) :)

i need solution.
 
to go from a:b:c to d:e:f you have to multiply each of a, b and c by some number k to get c, d and f

For example 2:4:7 = 20:40:70 where I multiplied the left set of numbers by k=10

Try to solve for x and y now. Please show us your work.
