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}$$=1\frac{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
