Question

1)3/4,1/2,3/5,3/10,9/20,2/25,9/50 бөлшектердін бөлімі 100-ге тең бөлшек түрінде жазыңдар. 2)2/3,1/2,3/4,1/6,4/15,7/20,11/30 бөлшектердің бөлімі 60-қа тең бөлшек түрінде жазыңдар.

Answer 1

Задание 1.

$\tt\displaystyle \frac{3}{4} =\frac{3*25}{4*25} =\frac{75}{100} \\\\\\\frac{1}{2}= \frac{1*50}{2*50} =\frac{50}{100} \\\\\\\frac{3}{5} =\frac{3*20}{5*20} =\frac{60}{100} \\\\\\\frac{3}{10} =\frac{3*10}{10*10} =\frac{30}{100} \\\\\\\frac{9}{20} =\frac{9*5}{20*5} =\frac{45}{100} \\\\\\\frac{2}{25} =\frac{2*4}{25*4} =\frac{8}{100} \\\\\\\frac{9}{50} =\frac{9*2}{50*2} =\frac{18}{100} \\\\\\$

Задание 2.

$\tt\displaystyle \frac{2}{3} =\frac{2*20}{3*20} =\frac{40}{60} \\\\\\\frac{1}{2} =\frac{1*30}{2*30} =\frac{30}{60} \\\\\\\frac{3}{4} =\frac{3*15}{4*15} =\frac{45}{60} \\\\\\\frac{1}{6} =\frac{1*10}{6*10} =\frac{10}{60} \\\\\\\frac{4}{15} =\frac{4*4}{15*4} =\frac{16}{60} \\\\\\\frac{7}{20} =\frac{7*3}{20*3} =\frac{21}{60} \\\\\\\frac{11}{30} =\frac{11*2}{30*2} =\frac{22}{60}$
