Step-by-step explanation:

If a, b and c are in proportion, then

a,b,b,c are in proportion.

This means that a:b = b:c

b = 15 and c = 40 , a = ?

Now,

Product of the extremes = Product of the means

So,

a × c = b × b

a × 40 = 15 × 15

a × 40 = 225

a = 225/40

\textbf{a = 5.625}a = 5.625

Hope it helps☺
