 СРОЧНО!!!

Answer 1

а) 1/10 + 7/100 = 10/100 + 7/100 = 17/100

б) 21/100 + 1/10 = 21/100 + 10/100 = 31/100

в) 3/5 + 9/10 = 6/10 + 9/10 = 15/10 = 3/2 = 1 1/2

г) 2/3 + 5/6 = 4/6 + 5/6 = 9/6 = 3/2 = 1 1/2

д) 15/24 + 3/8 = 15/24 + 9/24 = 24/24 = 1

е) 7/6 + 16/ 18 = 21/18 + 16/18 = 37/18 = 2 1/18

ж) 1/12 + 1/6 = 1/12 + 2/12 = 3/12 = 1/4

з) 1/2 + 3/10 = 5/10 + 3/10 = 8/10 = 4/5
