Answer 1

Question :

Are the following number in proportion.

16, 18,8,9

★ Solution:-

We have :-

$\sf{\large{16 : 18 :: 8 : 9 }}$

We know ,

$\underline{ \boxed{ \large{ \sf{Middle \: Term = Extreme \: Term}}}}$

$\underline{ \large{ \bf{16 \times 9 = 18 \times 8}}}$

$\underline{ \boxed{ \underline{ \bf { \red{ \large{144 = 144}}}}}}$

Hence, they are equal.

They are in proportion.
