Explicație pas cu pas:
c)
[tex] \frac{11}{3} + \frac{7}{8} \\ \frac{88}{24} + \frac{21}{24} = \frac{109}{24} [/tex]
d)
[tex]4 \frac{3}{5} - \frac{7}{8} \: \: = \: \: \frac{4 \times 5 + 3}{5} - \frac{7}{8} = \\ \frac{23}{5} - \frac{7}{8} = \: \frac{184}{40} - \frac{35}{40} = \frac{149}{40} [/tex]
e)
[tex] \frac{11}{3} \div \frac{33}{9} \\ \frac{99}{27} \div \frac{99}{27} = 1[/tex]
