Answer 1

hope this helps you...

Answer 2

$We \: have \: 2.4, 0.36 \:and \: 7.2$

$Convert \:the \:decimals \: into \: fraction \\form , we \:get \: \frac{24}{10}, \:\frac{36}{100}, \:and\\ \frac{72}{10}$

$HCF \: of \: numerators ( 24,36 \:and \: 72 )=12$

$LCM \: of \: denominators ( 10,100,10 ) = 100$

$Now, HCF \: of \: 2.4,0.36 \:and \: 7.2 \\= HCF \: of \: \frac{24}{10}, \frac{36}{100} \:and\: \frac{72}{10} \\\blue{= \frac{ H.C.F \: of \: numerators }{L.C.M \:of \: denominators } }\\= \frac{ 12}{100} \\= 0.12$

Therefore.,

$\red{ HCF \: of \: 2.4,0.36 \:and \: 7.2}\green {=0.12}$
