Question

Determine if the following is in proportion.

$33,44,75,100$

Answer 1

If $a,b,c,d$are in proportion then,

$a\times d=b\times c$

So, here we have $33,44,75,100$

in which

$a=33,b=44,c=75,d=100$

now, $33\times 100=3300$

and, $44\times 75=3300$

Hence $a\times d=b\times c$

So, $33,44,75,100$ are in proportion.
