Answer 1

I have given the answer now mark me as the brainleist and add a thanks

Answer 2

$\huge {\frac{1}{a} \ratio \frac{1}{b} \ratio \frac{1}{c} = 2 \ratio 3 \ratio5}$

$\huge {\frac {1}{a}= \frac{1}{2}}$

$\huge {\frac {1}{b} = \frac{1}{3}}$

$\huge {\frac{1}{c} = \frac{1}{5}}$

$\huge {\therefore a \ratio b \ratio c}$

$\huge {= \frac {1}{2} \ratio \frac {1}{3} \ratio \frac {1}{5}}$..... $\huge {(LCM)}$

$\huge {\frac {15\ratio 10 \ratio 6}{30}}$

$\huge {\therefore a \ratio b \ratio c = 15 \ratio 10 \ratio 6}$
