2,6:1½+1 5/10=.........

[tex]2.6 = \frac{26}{10} = \frac{13}{5} [/tex]
[tex]1 \frac{1}{2} = \frac{3}{2} [/tex]
[tex]1 \frac{5}{10} = \frac{15}{10} = \frac{3}{2} [/tex]
[tex] \frac{13}{5} \div \frac{3}{2} + \frac{3}{2} [/tex]
[tex] \frac{13}{5} \times \frac{2}{3} + \frac{3}{2} = \frac{26}{15 } + \frac{3}{2} = \frac{52}{30} + \frac{45}{30} = \frac{97}{30} = 3 \frac{7}{30} [/tex]

2,6 : 1 1/2 + 1 5/10 =
(2,6 : 1 1/2) + 1 5/10 =
(2,6 : 3/2) + 15/10 =
(2,6 : 1,5) + 1,5 =
1,73 + 1,5 =
3,23

semoga membantu:)
