Question

увеличте в 2 раза 1/6 3/4 5/8 1/2

Answer 1

$frac{1}{6} * 2 = frac{1}{6} * frac{2}{1} = frac{1*2}{6*1} = frac{2}{6} =frac{2:2}{6:2} = frac{1} {3} \ \ \ frac{3}{4} *2=frac{3*2}{4}= frac{6}{4} =1 frac{2}{4} =1 frac{1}{2} \ \ \ frac{5}{8} *2= frac{10}{8} =1 frac{2}{8} =1 frac{1}{4} \ \ \ frac{1}{2} *2= frac{2}{2} =1$

Answer 2

1/6*2=1/3,
3/4*2=3/2=1.5,
5/8*2=5/4=1.25,
1/2*2=1
