Hitunglah hasil dari operasi hiytung pecahan berikut

A. 1 2/3 – 4/5 + 0,25
=  1 2/3 – 4/5 + 1/4
=  1 40/60 – 48/60 + 15/60
=  1 7/60

b. 2,3 x 1,05
=  2 3/10 x 1 1/20
=  23/10 x 21/20
=  483/200
=  2 83/200 ( 2,415 )

c. 4 3/15 : 42
=  4 1/5 : 42
=  21/5 : 42
=  21/5 x 1/42
= 1/10

A. 5/3 - 4/5 + 25/100 = 25/100 – 8/100 + 25/100 = 267/100
b. 2,3 x 1,05 = 2,415
c. 4 3/15 : 42 = 63/15 x 1/42 = 63/630 = 1/10
