Question

А) 7/12+1/60 б) 19/65+14/13 в) 3/10+77/1000 г) 2/7+4/35 д) 21/32+1/8 е) 11/27+4/9

Answer 1

7/12 + 1/60 = 35/60 + 1/60 = 36/60 = 6/10 = 3/5
19/65 + 14/13 = 19/65 + 70/65 = 89\65 = 1целая 24/65
3/10 + 77/1000 = 0,3 + 0,077 = 0,377
2/7 + 4/35= 10/35 + 4/35 = 14/35
21/32 + 1/8 = 21/32 + 4/32 = 25/32
11/27 + 4/9 = 11/27 + 12/27 = 23/27

Answer 2

А)$\frac{7}{12}+ \frac{1}{60}= \frac{7*5+1}{60}= \frac{36}{60}= \frac{6}{10}$
б)$\frac{19}{65}+ \frac{14}{13}= \frac{19+14*5}{65 }= \frac{89}{65}$
в)$\frac{3}{10} + \frac{77}{1000}= \frac{3*100+77}{1000}= \frac{377}{1000}$
г)$\frac{2}{7}+ \frac{4}{35}= \frac{2*5+4}{35}= \frac{14}{35}= \frac{2}{5}$
д)$\frac{21}{32}+ \frac{1}{8}= \frac{21+4}{32}= \frac{25}{32}$
е)$\frac{11}{27}+ \frac{4}{9}= \frac{11+4*3}{27}= \frac{23}{27}$
