Question

Question:-
lia: b=7:9.b :(= 3:5. C: d = 3:7 and d is 25% more than e. find the ratio between a and e.​

Answer 1

We have to find ratio between a and e.

Step-by-step explanation:

Given: a:b=7:9, b:c=3:5, c:d=3:7, and d is 25% more than e.

ratios can also be written as dividing two numbers

as a:b can also be written as a divided by b

therefore first we have to calculate values for given data as

1. a=7b/9,
2. b=3c/5,
3. c=3d/7 and
4. d=5e/4 (as e + e/4=5e/4)

Now we just have to put values of d in 3. and then c in 2. then b in 1

.

we will get a=e/4.
