a._ 1/2*5/8+5/9=5/16+5/9
=(45+80)/144
=125/144
b._(2/3)/(6/10)-(8/18)=10/9-4/9
=(10-4)/9
=6/9 ,=>2/3
=>2)_ √(81/64); √81/√64= 9/8
a._(9/8 +5/8)/(15/2*3 -√(25/4²))
(13/8)/(45/2 -5/4)
(13/8)/(85/4)
13/870
b ._[(1/3 + 1/6)²]/[1/2 + √4/√9 - 1/6]
[(2+1)/(6)]²/(1/2 + 2/3 -1/6)
(3/6)²/1 = 1/9
3)._ a._[1836 + (12/100)1836]= 1836 + 5508/25
=2056
b._[12536 - (15/100)] = 12536 - 3/20
=(250 720-3)/20
=12535.85
