a. 3,25 : 5/16 + 3 5/8 x 32%
= 3,25 : 0,3125 + 3,625 x 0,32
= (3,25 : 0,3125) + (3,625 x 0,32)
= 10,4 + 1,16
= 11,56
b. 5/6 - 48‰ : 1 11/25 + 2,25
= 0,833 - 0,048 : 1,44 + 2,25
= 0,833 - (0,048 : 1,44) + 2,25
= 0,833 - 0,033 + 2,25
= 0,8 + 2,25
= 3,05
c. 7 : 8 1/6 - 3,2 + 3 1/7
= 7 : 8,167 - 3,2 + 3,143
= (7 : 8,167) - 3,2 + 3,143
= 0,857 - 3,2 + 3,143
= 0,8
