2\15
4\15
1\3
К знаменателю 30

Answer 1

2/15 = 2/2 * 2/15 = 4/30,

4/15 = 2/2 * 4/15 = 8/30,

1/3 = 1/3 * 10/10 = 10/30

Answer 2

$\frac{2}{15} = \frac{2 \times 2}{15 \times 2} = \frac{4}{30} \\ \\ \frac{4}{15} = \frac{4 \times 2}{15 \times 2} = \frac{8}{30} \\ \\ \frac{1}{3} = \frac{1 \times 10}{3 \times 10} = \frac{10}{30}$
