Answer 1

1) _______+3/12=3/4 
3/4 - 3/12 = _________
9/12 - 3/12 = ___________
6/12 = _________
1/2 = ________

1/2 + 3/12 = 3/4
6/12 + 3/12 = 9/12
9/12 = 9/12


2)_______-5/8=3/2
3/2 + 5/8 = _________
12/8 + 5/8 = _______
17/8 = ______

17/8 - 5/8 = 3/2
12/8 = 3/2
3/2 = 3/2


3)________-1/8=5/16 
5/16 + 1/8 = ________
5/16 + 2/16 = _________
7/16 = ________

7/16 - 1/8 = 5/16
7/16 - 2/16 = 5/16
5/16 = 5/16


4)___________+5/6=4/3
4/3 - 5/6 = _______
8/6 - 5/6 = ________
3/6 = ________
1/2 = _______

3/6 + 5/6 = 4/3
8/6 = 4/3
2/3 = 4/3

Answer 2

1) _______+3/12=3/4:

$x+ \frac{3}{12} = \frac{3}{4}$

$x+ \frac{1}{4} = \frac{3}{4}$

$x= \frac{3}{4} - \frac{1}{4}$

$x= \frac{1}{2}$

Respuesta(1): $\frac{1}{2}$.

2)_______-5/8=3/2:

$x- \frac{5}{8} = \frac{3}{2}$

$x= \frac{3}{2} + \frac{5}{8}$

$x= \frac{12+5}{8}$

$x= \frac{17}{8}$

Respuesta(2): $\frac{17}{8}$

3)________-1/8=5/16: 

$x- \frac{1}{8} = \frac{5}{16}$

$x= \frac{5}{16} + \frac{1}{8}$

$x= \frac{5+2}{16}$

$x= \frac{7}{16}$

Respuesta(3): $\frac{7}{16}$

4)___________+5/6=4/3:

$x+ \frac{5}{6} = \frac{4}{3}$

$x= \frac{4}{3} - \frac{5}{6}$

$\frac{8-5}{6}$

$\frac{3}{6}$

$\frac{1}{2}$

Respuesta(4): $\frac{1}{2}$

Espero que te sirva. :)
