Answer 2

Answer:

Please make me a brainliest.

1.

$\frac{5}{4} = \frac{5 \times 4}{4 \times 4} = \frac{5 \times 5}{4 \times 5} = \frac{5 \times 3}{4 \times 3} \\ \\ \frac{5}{4 } = \frac{20}{16} = \frac{25}{20} = \frac{15}{12}$

2.

$\frac{ - 3}{7} = \frac{ - 3 \times 2}{7 \times 2} = \frac{ - 3 \times - 3}{7 \times - 3} = \frac{ - 3 \times 2}{ 7 \times 2} \\ \\ \frac{ - 3}{7} = \frac{ - 6}{14} = \frac{9}{ - 21} = \frac{ - 6}{14}$

Please please mark me as a brainliest.

Thank you.
