Answer:

Step-by-step explanation:

If a,b,c,d are in proportion

ad=bc

Let the third proportion be x

(4/9)x = (8/5 × 1/5)

(4/9)x = (8/25)

X = (8/25) × (9/4)

X = (72/100)

X = 18/25

Answer 2

Answer:

Let the missing fraction be f, then as per formula

f×(4/9)=(8/5)×(1/5)

f=(8/25)/(4/9)

=8×9/(4×25)

=18/25 Ans
