Answer 1

2/5 +0,77= 0,4 + 0,77 = 1,17
15,4+3 1/3= 154/10 + 10/3 = 77/5 + 10/3 = 231/15 +50/15 = 281/15 = 18,7(3)
1,75- 5/6= 7/4 - 5/6 = 21/12 - 10/12 = 11/12 = 0,91(6)
3 1/5-2,25= 16/5 - 9/4 = 64/20 - 45/20 = 19/20 = 0,95
8 3/4+1,125= 35/4 +9/8 = 70/8 + 9/8 = 79/8 = 9,875

Answer 2

2/5 + 0,77 = 2/5 + 77/100 = 40/100 + 77/100 = 117/100 =1,75

15,4 + 3 1/3 = 15 4/10 + 3 1/3 = 154/100 + 10/3 = 77/5 + 10/3 = 231/15 + 50/15 = 281/15

1,75 - 5/6 = 175/100 - 5/6 = 7/4 - 5/6 = 42/24 - 20/24 = 22/24 = 11/12

3 1/5 - 2,25 = 16/5 - 225/100 = 16/5 - 9/4 = 64/20 - 45/20 = 19/20

8 3/4 + 1,125 = 35/4 + 1125/1000 = 35/4 + 9/8 = 280/32 + 36/32 = 316/32 = 79/8 = 9 7/8
