Answer 1

Answer:

OK

Step-by-step explanation:

1)25/8*2/5-3/5*-10/9 can be written as

5/4 -(-2/3) (now solving these by subtraction)

5/4+2/3

15+8/12

23/12

2)1/2*1/4+1/2*6

1/8+3

1+24/8

25/8

3)-5*2/15-(-6*2/9)

-2/3-(-4/3)

-2/3+4/3

-2+4/1

2/1

2

4)-9/4*5/3+13/2*5/6

-15/4+65/12

-45+65/12
