Question

proportion 8m:21mand rs 24:rs 63​

Answer 1

$If \: a,b ,c\: and\: d \: are \: in \: proportion \\then\: a : b = c : d$

$Here, a = 8 \: m , b = 21 \: m \\ and \: c = Rs \: 24 , \: d = Rs \: 63$

$i) \frac{ a}{ b }\\= \frac{8 \: m }{ 21 \: m } \: --(1)$

$ii ) \frac{ c} { d } \\= \frac{ Rs \: 24 }{ Rs \: 63 } \\= \frac{ 3 \times 8 }{ 3 \times 21 } \\= \frac{8}{21} \: --(2)$

$From \: (1) \: and\: (2) , we \: get$

$(1) = (2)$

Therefore.,

$\green { 8\: m : 21 \: m \:and \: Rs \:24 :Rs \: 63}\\\green { are \: in \: proportion }$
