Answer 1

{1 1/2 - [(6 1/2 - 4 3/4 ) : (5- 1/3 ) + 1/2 ]} : 5/8 =
= {3/2 - [(13/2 - 19/4) : (15/3 - 1/3) + 1/2]} : 5/8 = 
= {3/2 - [(26/4 - 19/4) : 14/3 + 1/2]} : 5/8 = 
= {3/2 - [7/4 : 14/3 + 1/2]} : 5/8 = 
= [3/2 - (7/4 * 3/14 + 1/2)] : 5/8 = 
= [3/2 - (3/8 + 1/2)] : 5/8 = 
= [3/2 - (3/8 + 4/8)] : 5/8 = 
= [3/2 - 7/8] : 5/8 =
= (12/8 - 7/8) * 8/5 = 
= 5/8 * 8/5 = 
= 1
