----------------------------------------------------------------------------------
(46 * 2/15) * 15/23 = 46 * (2/15 * 15/23) = 46 * 2/23 = 2 * 2 = 4

(5/16 * 13/18) * (18/26 * 16/25) = (5/16 * 16/25) * (13/18 * 18/26) = 5/25 * 13/26 = 1/5 * 1/2 = 1/10 

32/33 * 52/53 * (53/52 * 33/34) = (32/33 * 33/34) * (52/53 * 53/52) = 32/34 * 1 = 16/17

Verified answer

(46*2/15) * 15/23=(46*2*15)/(15*23)=(46*2)/23=2*2=4
(5/16*13/18)* (18/26*16/25)=(5*13*18*16)/(16*18*26*25)=(5*13)/(26*25)=1/(2*5)=1/10=0,1
32/33*52/53*(53/52*33/34)=(32*52*53*33)/(33*53*52*34)=32/34=16/17
