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]
