1. 8 3/5 + 3,75 : ( 350% - 1 5/8 )
= 8 3/5 + 3,75 : ( 350/100 - 13/8 )
= 8 3/5 + 3,75 : ( 1400/400 - 650/400 )
= 8 3/5 + 3,75 : 750/400
= 8 3/5 + 375/100 x 400/750
= 8 3/5 + 150.000/75.000
= 43/5 + 150.000/75.000
= 645.000/75.000 + 150.000/75.000
= 795.000/75.000
= 159/25

2. 15/1 - 7 1/8 - 90% x 4,6
= 15/1 - 7 1/8 - 90/100 x 46/10
= 15/1 - 57/8 - 4140/1000
= 120/8 - 57/8 - 4140/1000
= 63/8 - 4140/1000
= 7875/1000 - 4140/1000
= 3735/1000
= 747/200
= 3 47/200

1. 8,6 + 3,75 : [3,5 - 1,625]
= 8,6 + 3,75 : 1,875
= 8,6 + 2 = 10,6

2. 15 - 7,125 - 0,9 × 4,6
= 15 - 7,125 - 4,14
= 3,735
