a.satu 2 per 3-4 per 5+0,25
b.2,3 kali 1,05
c.empat 3 per 15bagi 42
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
