Scrie fractiile 9 pe 10,6 pe 7 si 15 pe 100 ca suma de trei fractii. Pentru fiecare caz scrie cate 3 solutii.

A.
1.[tex] \frac{5}{10} + \frac{3}{10}+ \frac{1}{10} = \frac{9}{10} [/tex]
2.[tex] \frac{4}{10} + \frac{1}{10} + \frac{4}{10} = \frac{9}{10} [/tex]
3.[tex] \frac{2}{10} + \frac{6}{10} + \frac{1}{10} = \frac{9}{10} [/tex]
B.
1.[tex] \frac{1}{7}+ \frac{1}{7} + \frac{4}{7} = \frac{6}{7} [/tex]
2.[tex] \frac{2}{7}+ \frac{2}{7} + \frac{2}{7}= \frac{6}{7} [/tex]
3.[tex] \frac{3}{7} + \frac{2}{7} + \frac{1}{7} = \frac{6}{7} [/tex]
C.
1.[tex] \frac{5}{100} + \frac{5}{100} + \frac{5}{100} = \frac{15}{100} [/tex]
2.[tex] \frac{11}{100}+ \frac{3}{100} + \frac{1}{100} = \frac{15}{100} [/tex]
3.[tex] \frac{10}{100}+ \frac{4}{100}+ \frac{1}{100}= \frac{15}{100} [/tex]
