Answer 1

Answer:

A:D = 2:5

Step-by-step explanation:

I think it is right

Answer 2

Step-by-step explanation:

A/B =2/3 let it equation 1

B/c = 2/4 equation 2

c/d = 2/5 equation 3

we have to find A/D =??

solve equation 2 and 3

substitute c= 2d/5 from equation 3 in equation 2

we get b/d =1/5 let it be equation 4

substitute b=d/5 from equation 4 in equation 1

then we get a/d = 2/15

or u can do this way

multiply equation 2 and equation 3

then we get b/d = 1/5

multiply the above relation with eq 1

u get A/d = 2/15
