5. 20 - 2 3 per 4(campuran) =
6.16 per 12 - 3 per 8 - 1 per 6 =
Tolong sama penjelasannya ya :)

Answer 1

1. 2 4/5 - 1 1/3 - 1/5
di ubah menjadi pecahan biasa = 14/5 -4/3-1/5
kpk =42/15 - 20/15 -3/15
= 19/15= 1 4/5

2.   6 5/10 -3 1/4 - 1 2/10
   = 65/10 -13/4 - 12/10
kpk = 130/20 - 65/20 -24/20
    =40/20 = 2

3.  8 - 4 2/5 
= 8 - 22/5
kpk=40/5 - 22/5
= 18/5 = 3 3/5

4. 15- 7/2
kpk= 30/2 - 7/2
=23/2=11 1/2

5.20-2 3/4=
=20/1 -11/4
kpk= 80/4-11/4
=69/4=17 1/4

6.16/12-3/8 1/6
kpk=32/24 -9/24-4/24
=19/24
