$10)3\frac{7}{39}+1\frac{5}{26}=3\frac{14}{78}+1\frac{15}{78}=4\frac{29}{78}$

$11)4\frac{5}{21}+3\frac{11}{18}=4\frac{30}{126} +3 \frac{77}{126} =7\frac{107}{126}$

$12)4\frac{5}{12}+5\frac{13}{20}=4\frac{25}{60}+5\frac{39}{60}=9\frac{64}{60}=10\frac{4}{60}=10\frac{1}{5}$

$13)1\frac{7}{8}+1\frac{1}{8}=2\frac{8}{8}=3$

$14)5\frac{3}{4}+1\frac{1}{4}=6\frac{4}{4}=7$

$15)2\frac{2}{13}+4\frac{11}{13}=6\frac{13}{13}=7$

Пошаговое объяснение:

10)  3 7/39 + 1 5/26 = 4 29/78

11)  4 5/21 + 3 11/18 = 7 107/126

12)  4 5/12 + 5 13/20 = 9 64/60 = 10 4/60 = 10 1/15

13)  1 7/8 + 1 1/8 = 2 8/8 = 3

14)  5 3/4 + 1 1/4 = 6 4/4 =7

15)  2 2/13 + 4 11/13 = 6 13/13 = 7

16)  4 7/12 + 5 5/8 = 9 29/24 = 10 5/24
