Answer 1

1. 24 1/8 : 1 1/4 - 10 1/5 * 3/10 = 193/8 * 4/5 - 51/5 * 3/10 = 193/10 - 153/50 = 19 3/10 - 3 3/50 = 19 15/50 - 3 3/50 = 16 6/25 (po skróceniu)

Answer 2

24i1/8 : 1i1/4 - 10i1/5 * 3/10 = 24,125 : 1,25 - 10,2*0,3 = 19,3 - 3,06 = 16,24

 

18i1/4 - 12 i4/7 + 3i2/5 -1i3/8 = 18 i 70/280 - 12 i 160/280 + 3 i 112/280 -1i105/280 = 21 i 182/280 - 13 i 265/280 = 20 i 462/280 - 13i265/280 =

7 i 197/280

 

 

150 + 32i1/4 *3i1/2 + 8i1/5 : 3 i1/10 = 150 + 129/4*7/2 + 41/5:31/10 = 

150 + 903/8+41/5*10/31 = 150+ 903/8 + 41/1*2/31= 150 + 903/8 + 82/31=

=150+ 112i7/8 + 2 i 20/31 = 150+112 i 217/248 + 2i 160/248 = 264 i 377/248

= 265 i 129/248
