7 2/4 + 4 1/8 - 1,4 x 20%
= 7,5 + 4,125 - 1,4 x 0,2
= 11,625 - 0,28
= 11,345
= 11 345/1.000
= 11 69/200

Answer 2

Langsung diubah ke pecahan biasa
= 30/4 + 33/8 - 14/10 x 20/100
= Penyebut (4) & (8) dicari KPK
KPK 4 & 8 adalah 16
= 30 x 4/16 = 120/16
= 33 x 2/16 = 66/16
= 120 + 66/16 = 186/15 = 12 6/15

= 14/10 x 20/100
= 28/100
= 186/15 - 28/100
= 18600 - 520/1500
= 18080/1500 = 12,05
