Answer 1

Answer:

hey mate hope this will help you

Answer 2

SOLUTION:-

To Find:-

$L.C.M \:of \:\frac{1}{5},\frac{3}{7},\frac{7}{10}$

Formula:-

$LCM \:of \:a\:fraction = \frac{LCM \:of \:numerator}{HCF \:of \:denominator}$

By The Problem:-

$LCM = \frac{LCM \:of\: 1,3,7}{HCF \: of \:5,7,10} \\ \\ \implies LCM = \frac{21}{1} \\ \\ \implies LCM = 1$

Answer:-

LCM = 1

Focus Zone:-

LCM of 1,3,7 = 21

HCF of 5,7,10 = 1
