Question

If a : b=c:d=e: f= 2:1, then
(a + 2c + 3e): (5b + 10d + 15f) is equal to:​

Answer 1

Answer:

= 2

5

Step-by-step explanation:

GIVEN

a:b=c:d=e:f=2:1

TO DETERMINE

(a + 2c + 3e) : (5b + 10d + 15f)

EVALUATION

It is given that

a:b=c:d=e:f=2:1;

=》a b = c d = e f = 2 1

=》a=2b,c=2d , e = 2f

Hence

(a + 2c + 3e) : (5b + 10d + 15f)

= (a + 2c + 3e)

(5b+; 5b+10d+15f)

= (2b+4d+6f)

(5b+10d+15f)

= 2(b + 2d + 3f)

5(b + 2d + 3f)

= 2

Answer 2

Answer:

If a : b=c:d=e: f= 2:1

Then,

a=2b,c=2d and e=2f. ————(i)

The value of :—

(a + 2c + 3e): (5b + 10d + 15f)

=(2b+4d+6f):(5b+10d+15f)

=2(b+2d+3f):5(b+2d+3f)

=2:5
