Answer 1

1) a=2
$frac{2}{5} = frac{6}{15} \ frac{2*3}{5*3} = frac{6}{15} \ frac{6}{15}=frac{6}{15}$
2) a=48
$frac{1}{12}= frac{4}{48} \ frac{1*4}{12*4} = frac{4}{48} \ frac{4}{48}=frac{4}{48}$
3) a=10
$frac{56}{70} = frac{8}{10} \ frac{56:7}{70:7} = frac{8}{10} \ frac{8}{10} =frac{8}{10}$
4) a=72
$frac{72}{60} = frac{6}{5} \ frac{72:12}{60:12} = frac{6}{5} \ frac{6}{5} =frac{6}{5}$
