Explicación paso a paso:
a.) 3,45 - 7/10
311/90 - 7/10
311/90 - 63/90
248/90 ....(simplificando)
124/45
b.) 1,2 + 2,3 + 3,45
12/10 + 21/9 + 311/90
108/90 + 210/90 + 311/90
629/90
a)
[tex]3.45 - \frac{7}{10} = \ \frac{69}{20} - \frac{7}{10} = \frac{69 - 14}{20} = \frac{55}{20} = \frac{11}{4} [/tex] = 2,75
b)
[tex]1.2 + 2.3 + 3.45 = \frac{6}{5} + \frac{23}{10} + \frac{69}{20} = \frac{24 + 16 + 69}{20} = \frac{139}{20} [/tex] = 6,95
