Question

1. Simplify the following rational numbers:

() (25/8 x 2/5) (3/5x -10/9)

(i) (1/2 x 4)+ (1/2 x 6)

(ii) (-5 x 2/15) (-6 x 2/9)

(iv) (-9/4 x 5/3) + (13/2 x 5/6)

2. Simplify the rational expressions:

() (3/2* 1/6) + (5/3 x 7/2) - (13/8 x 4/3)

(i) (1/4 x 2/7)-(5/14 x-2/3) + (3/7x 9/2)

(i) (13/9 x-15/2) + (7/3 x 8/5) + (3/5 x )

(iv) (3/11 x 5/6) (9/12 x 4/3) + (5/13 x 6/15)

3. Find the value and express as a rational number in standard form

() 2/5+26/15

(i) 10/3+ (-35/12)

(i)-6+(-8/17)

(iv) 40/98+ (-20)
