Question

3/8 + х = 1/2 2) х – 1/8 = 8/9 3) 2/3 – х =4/9

Answer 1

1) $frac{3}{8}+x=frac{1}{2}$

$x=frac{1}{2}-frac{3}{8}$

$x=frac{1}{8}$

2) $x-frac{1}{8}=frac{8}{9}$

$x=frac{8}{9}+ frac{1}{8}$

$x=frac{64+9}{72}$

$x=frac{73}{72}$$=1frac{1}{72}$

3) $frac{2}{3}-x=frac{4}{9}$

$x=frac{2}{3}-frac{4}{9}$

$x=frac{2}{9}$

Answer 2

1) х = 1/2-3/8=4/8-3/8=1/8

2) x=8/9+1/8=64/72+9/72=73/72

3) x=2/3-4/9=6/9-4/9=2/9
