Question

Сократите обыкновенные дроби
1) 10*3/23*10;
2) 10*2/21*30;
3)4*5/15*16;
4)8*9/27*16

Answer 1

1)30/230=3/23
2)20/630=2/63
3)20/240=1/12
4)72/432=1/6

Answer 2

$\frac{8}{9} \div \frac{27}{16} = \frac{3}{2} = 1 \frac{1}{2}$

$\frac{10}{3} \div \frac{23}{10} = \frac{23}{3 }$

$\frac{10}{2} \div \frac{21}{30} = \frac{7}{6} = 1 \frac{1}{6}$

$\frac{4}{5} \div \frac{15}{16} = \frac{3}{4}$
