Question

Помогите
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 = 8965 = 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)$frac{11}{27}+ frac{4}{9}= frac{11+4*3}{27}= frac{23}{27}$
