Answer:

1.

[tex] \frac{1}{4} + \frac{1}{4} = \frac{2}{4} = \frac{1}{2} [/tex]

2.

[tex] \frac{6}{10} - \frac{3}{10} = \frac{3}{10} [/tex]

3.

[tex]1 + 1 + \frac{3}{5} = \frac{5 + 5 + 3}{5} = \frac{13}{5} [/tex]

4.

[tex]1 + 1 - \frac{5}{12} = \frac{12 + 12 - 5}{12} = \frac{19}{12} [/tex]

5.

[tex]1 - \frac{5}{12} + 1 - \frac{3}{12} [/tex]

lets add first:

[tex] \frac{5}{12} + 1 = \frac{5 + 12}{12} = \frac{17}{12} [/tex]

the subtract:

[tex]1 - \frac{17}{12} = \frac{12 - 17}{12} = - \frac{5}{12} [/tex]

subtract -3/12

[tex] - \frac{5}{12} - \frac{3}{12} = - \frac{8}{12} [/tex]
