Answer 1

1.   $\frac{1}{8} + \frac{1}{16}=$ $\frac{16}{16} +\frac{8}{16} =\frac{24}{16}$

2. $\frac{6}{15} -\frac{6}{10} = \frac{60}{30} - \frac{90}{30} = -\frac{30}{30}$   osea le falta 0 por leer

3. $\frac{2}{3} + \frac{1}{5} = \frac{3}{15} + \frac{10}{15} = \frac{13}{15}$ no prefiere la musica tropical

4. $2\frac{3}{10} - 1\frac{1}{2} -\frac{2}{5} = \frac{2}{5}$ es lo que sobro

y lo que utilizo : $1\frac{1}{2} + \frac{2}{5} =\frac{3}{2} +\frac{2}{5} = \frac{15}{10} +\frac{4}{10} = \frac{19}{10}$

5.

a) $\frac{2}{4} +\frac{7}{2} +\frac{3}{8} = (\frac{2}{4} +\frac{7}{2}) + \frac{3}{8} = \frac{4}{8}+ \frac{28}{8} +\frac{3}{8}= \frac{35}{8}$

b) $\frac{15}{9} -\frac{7}{3} = \frac{45}{9} - \frac{63}{9}= -\frac{18}{9}$

c) $\frac{8}{3}+\frac{2}{5}-\frac{4}{45} = (\frac{8}{3}+\frac{2}{5})- \frac{4}{45}= \frac{46}{15}- \frac{4}{45}= \frac{2070}{45} - \frac{675}{45} = \frac{1395}{45}$

d) $\frac{8}{4}-\frac{3}{2}+\frac{1}{8}=(\frac{8}{4}-\frac{3}{2}) + \frac{1}{8} = (\frac{16}{8}-\frac{12}{8})+ \frac{1}{8} = \frac{4}{8} +\frac{1}{8} =\frac{5}{8}$
