Question

if a:b=1:2,b:c=6:5 and c:d=2:3, find a:d

Answer 1

Hey! Here is ur answer...


a/b = 1/2
b = 2a
Now, b/c = 6/5
2a/c = 6/5
a/c = 3/5
c/a = 5/3
c = 5a/3
And, c/d = 2/3
5a/3d = 2/3
5a/d = 24/3
5a/d = 2
a/d = 2/5
So, a:d = 2:5

Hope this will help u...Plz mark it as brainliest... :)

Answer 2

a/b=1/2
b/c=6/5
c/d=2/3
÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷
multiply all we get
÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷
a/b×b/c×c/d=1/2× 6/5×2/3

a/d = 2/5
a:d = 2:5
hope it helps you , be Happy
