Find X/Y = ratio X : Y
See 3 Answers
X/3 = Y/6
X/Y = 3/6 = 1/2
Therefore, ratio
X : Y = 1 : 2
X/Y = 3/6 = 1/2
Therefore, ratio
X : Y = 1 : 2
Could you explain, how you bring X/Y=3/6
Thank you.
Thank you.
Alternative, but closely related, line of thought
x/3 = y/6
2x/6 = y/6
Then of course the numerators are the same.
2x = y
y is twice of x
So, ratio y : x is 2 : 1
And ratio x : y is 1 : 2
x/3 = y/6
2x/6 = y/6
Then of course the numerators are the same.
2x = y
y is twice of x
So, ratio y : x is 2 : 1
And ratio x : y is 1 : 2
Using AC Lim’s approach,
x/3 = y/6
If we perform cross multiplication,
6x = 3y
2x = 1y
If we do cross division (read up on it),
x/y = 1/2
So the ratio x : y = 1 : 2
x/3 = y/6
If we perform cross multiplication,
6x = 3y
2x = 1y
If we do cross division (read up on it),
x/y = 1/2
So the ratio x : y = 1 : 2
Thank you so much for your explanation. I understood now.
