Penjelasan dengan langkah-langkah:

A. 3/4 - 1/2 + 1/4 = 3/4 - 2/4 + 1/4

= 3-2+1/4

= 2/4 : 2

= 1/2

B. 4/7 - (1/4 : 1/2) = 4/7 - (1/4×2/1)

= 4/7 - 2/4

= 16/28 - 14/28

= 2/28 : 2

= 1/14

C. 0,75 +(1,43 × 5,16) = 0,75 + 7,3788

= 8,1288

D. 2/3 + 1/7 : 0,6 = 2/3 + (1/7 : 6/10)

= 2/3 + (1/7 × 10/6)

= 2/3 + 10/42

= 28/42 + 10/42

= 38/42 : 2

= 19/21
