Question

check whether 2.5, 12.5, 62.5 are in continued proportion or not​

Answer 1

Step-by-step explanation:

if a b and c are in continued proportion

b²=ac

here

a=2.5

b=12.5

c=62.5

LHS=b²

=12.5²

=156.25

RHS=ac

=62.5*2.5

=156.25

LHS=RHS

hence the nos. are in continued proportion

Answer 2

Answer:

Step-by-step explanation:

Let 2.5 be a, 12.5 be b and 62.5 be c.

To be in continued proprtion,

b² = ac

Here,

12.5*12.5 = 2.5*62.5

156.25 = 156.25

Therefore, 2.5, 12.5 and 62.5 are in continued proportion.
