Answer 1

a) $\frac{1}{2} + x = \frac{5}{6}$

x = 5/6 - 1/2

x = 1/3

b) x + 1/4= 3/4

x = 3/4 - 1/4

x = 1/2

c) x - 1/5 = 3/10

x = 3/10 + 1/5

x = 1/2

d) 5/6 - x = 1/3

x = 5/6 - 1/3

x = 1/2

e)

3/10 + x =1/2

x = 1/2 - 3/10

x = 1/5

g)

x + 1/4 = 3/8

x = 3/8 - 1/4

x = 1/8

Answer 2

a,

$\frac{1}{2} + x = \frac{5}{6} x = \frac{5}{6} - \frac{1}{2} x = \frac{5}{6} - \frac{3}{6} x = \frac{2}{6} x = \frac{1}{3} b, x + \frac{1}{4} = \frac{3}{4} x = \frac{3}{4} - \frac{1}{4} x = \frac{2}{4} x = \frac{1}{2} c, x - \frac{1}{5} = \frac{3}{10} x = \frac{3}{10} + \frac{1}{5} x = \frac{3}{10} + \frac{2}{10} x = \frac{5}{10} x = \frac{1}{2} d, \frac{5}{6} - x = \frac{1}{3} x = \frac{5}{6} - \frac{1}{3} x = \frac{5}{6} - \frac{2}{6} x = \frac{3}{6} x = \frac{1}{2} e, \frac{3}{10} + x = \frac{1}{2} x = \frac{1}{2} - \frac{3}{10} x = \frac{5}{10} - \frac{3}{10} x = \frac{2}{10} x = \frac{1}{5} g, x + \frac{1}{4} = \frac{3}{8} x = \frac{3}{8} - \frac{1}{4} x = \frac{3}{8} - \frac{2}{8} x = \frac{1}{8}$

Answer 3

a,

$\frac{1}{2} + x = \frac{5}{6} x = \frac{5}{6} - \frac{1}{2} x = \frac{5}{6} - \frac{3}{6} x = \frac{2}{6} x = \frac{1}{3} b, x + \frac{1}{4} = \frac{3}{4} x = \frac{3}{4} - \frac{1}{4} x = \frac{2}{4} x = \frac{1}{2} c, x - \frac{1}{5} = \frac{3}{10} x = \frac{3}{10} + \frac{1}{5} x = \frac{3}{10} + \frac{2}{10} x = \frac{5}{10} x = \frac{1}{2} d, \frac{5}{6} - x = \frac{1}{3} x = \frac{5}{6} - \frac{1}{3} x = \frac{5}{6} - \frac{2}{6} x = \frac{3}{6} x = \frac{1}{2} e, \frac{3}{10} + x = \frac{1}{2} x = \frac{1}{2} - \frac{3}{10} x = \frac{5}{10} - \frac{3}{10} x = \frac{2}{10} x = \frac{1}{5} g, x + \frac{1}{4} = \frac{3}{8} x = \frac{3}{8} - \frac{1}{4} x = \frac{3}{8} - \frac{2}{8} x = \frac{1}{8}$
