Võ Ngọc Phương · Accepted Answer

Ta có:

$\dfrac{1}{2}=\dfrac{1.24}{2.24}=\dfrac{24}{48}$

$\dfrac{5}{-8}=\dfrac{\left(-5\right).6}{8.6}=\dfrac{-30}{48}$

$\dfrac{35}{28}$ -> không thể có mẫu bằng 48 được. ( kiểm tra )

$\dfrac{-9}{12}=\dfrac{\left(-9\right).4}{12.4}=\dfrac{-36}{48}$

$\dfrac{7}{-16}=\dfrac{\left(-7\right).3}{16.3}=\dfrac{-21}{48}$

$\dfrac{33}{88}=\dfrac{3}{8}=\dfrac{3.6}{8.6}=\dfrac{18}{48}$

$\dfrac{1}{2}=\dfrac{1\times24}{2\times24}=\dfrac{24}{48}$

$\dfrac{5}{-8}=\dfrac{5\times\left(-6\right)}{-8\times\left(-6\right)}=\dfrac{-30}{48}$

$\dfrac{35}{28}=\dfrac{5}{4}=\dfrac{5\times12}{4\times12}=\dfrac{60}{48}$

$\dfrac{-9}{12}=\dfrac{-9\times4}{12\times4}=\dfrac{-36}{48}$

$\dfrac{7}{-16}=\dfrac{7\times\left(-3\right)}{-16\times\left(-3\right)}=\dfrac{-21}{48}$

$\dfrac{33}{88}=\dfrac{3}{8}=\dfrac{3\times6}{8\times6}=\dfrac{18}{48}$Câu trả lời: $\dfrac{1}{2}=\dfrac{1\times24}{2\times24}=\dfrac{24}{48}$

$\dfrac{5}{-8}=\dfrac{5\times\left(-6\right)}{-8\times\left(-6\right)}=\dfrac{-30}{48}$

$\dfrac{35}{28}=\dfrac{5}{4}=\dfrac{5\times12}{4\times12}=\dfrac{60}{48}$

$\dfrac{-9}{12}=\dfrac{-9\times4}{12\times4}=\dfrac{-36}{48}$

$\dfrac{7}{-16}=\dfrac{7\times\left(-3\right)}{-16\times\left(-3\right)}=\dfrac{-21}{48}$

$\dfrac{33}{88}=\dfrac{3}{8}=\dfrac{3\times6}{8\times6}=\dfrac{18}{48}$
