Answer 1

Ответ:

4 3\8+(-1\4)=4 3/8-1/4=4 3/8-2/8=4 1/8

3 3\8 + (-9 2\1)=3 3/8-9 1/2=3 3/8-

9 4/8=-6 1/8

3 2\15+(-9 1\3)=3 2/15-9 1/3=3 2/15-

9 5/15=-6 1/5

Answer 2

1) 4 + 3/8 + (-1/4) First, convert 4 to a fraction with a common denominator of 8: 4 = 32/8 Now the expression becomes: 32/8 + 3/8 - 2/8 = 33/8 - 2/8 = 31/8

2) 3 + 3/8 + (-9 + 1/2) First, convert 3 to a fraction with a common denominator of 8: 3 = 24/8 Now the expression becomes: 24/8 + 3/8 - 72/8 + 4/8 = -45/8

3) 3 + 2/15 + (-9 + 1/3) First, convert 3 to a fraction with a common denominator of 15: 3 = 45/15 Now the expression becomes: 45/15 + 2/15 - 135/15 + 5/15 = -83/15

Therefore, the answers are: 1) 31/8 2) -45/8 3) -83/15
