Question

determine whether the following are in proportion or not
step by step​

Answer 1

$\Huge {\boxed {\boxed {\green {\mathbb { Answer:}}}}}$

$\tt{ 3 , 4\frac{1}{2} , 2\frac{2}{3} , 4 }$

ᴛʜᴇᴏʀᴇᴍ :

ɪɴ ᴘʀᴏᴘᴏʀᴛɪᴏɴᴀʟ ɴᴜᴍʙᴇʀs,

ᴛʜᴇ ᴘʀᴏᴅᴜᴄᴛ ᴏғ ᴇxᴛʀᴇᴍᴇ = ᴛʜᴇ ᴘʀᴏᴅᴜᴄᴛ ᴏғ ᴍᴇᴀɴ

Thus,

$\tt{Product \: of \: extreme = 3 \times 4 = <strong>12</strong> }$

$\tt{Product \: of \: mean = \frac{\cancel{9}}{ \cancel{2} } \times \frac{\cancel{8} }{\cancel{3} } = 12 }$

$\large{\boxed{\blue{\bf{12=12}}}}$

$\small{\boxed{\red{\bf{ Product \: of \: extreme = Product \: of \: mean}}}}$

$\small{\boxed{\pink{\bf{Hence, \: the \: numbers \: are \: in \: proportion}}} }$
