Simple calculation, the process of calculation, because it is a recursive equation 10 of 27 x 18 x 5 of 3, 11 of 13 x 11 of 26 + 2 of 13 6:5x15:8 × 4:3:13:7x4 + 13:6x4 (7 / 18 + 5 / 9) x 35 / 27 99 x 100 / 1
(10/27)*18*(3/5)
=(10*18*3)/(27*5)
=(2 * 2 * 1) / (1 * 1) approximate score
=4
(11/13)(26/11)+2/13
=26/13+2/13
=28/13
(5/6)*(8/15)*(3/4)
=(5*8*3)/(6*15*4)
=(1*1*1)/(1*3*1)
=1/3
(7/13)*4+(6/13)*4
=(7 / 13 + 6 / 13) * 4 combination law
=1*4
=4
(7/18+5/9)*(27/35)
=(7/18+10/18)*(27/35)
=(17/18)(27/35)
=17*27/(18*35)
=17*3/(2*35)
=51/70
99*(1/100)
=99/
