выполните сложение: 2 7/10+9 2/15;
3 1/12+4 2/15
1 7/12+3 5/9;

Answer 1

1)

$(2 + 9) + ( \frac{7}{10} + \frac{2}{15}) = 11 + \frac{5}{6} = 11 \frac{5}{6}$

2)

$(3 + 4) + ( \frac{1}{2} + \frac{2}{15}) = 7 + \frac{13}{60} = 7 \frac{73}{60}$

3)

$(1 + 3) + ( \frac{7}{12} + \frac{5}{9}) = 4 + \frac{41}{36} = 4 + 1 \frac{5}{36 } = 5 \frac{5}{36}$
