Question

1.Tentukan hasil dari:
a. (-8 + 7) - (-7 +18 -19) - (24) =
b. (80 - (-25) + 24 - 27 + (-18 - 12)=
2. Tentukan FPB dan KPK dari 14,24, dan 32!

Answer 1

1. (-8+7) - (-7+18-19) -(24)
=-1 -(-8) -24
=-17

2. (80-(-25) +24 - 27 + (
-18-12)
= 80+25+24-27-18-12
=129-57
=72
3. Dicarai faktor dari masing² bilangan
14=2x7
24=2x2x2x3
32=2x2x2x2x2
maka
fpb=2
kpk=2^5x3x7=672
semoga bermanfaat :)

Answer 2

(-8+7) - (-7+18-19) - (24)
= -1 - (-8) - (24)
= -17

80 - (-25) + 24 - 27 + (-18-12)
= 105 + 24 - 27 + (-30)
= 72

14     24     32(:2)
07     12     16 (:2)
07     06     08 (:2)
07     03     04 (:2)
07     03     02 (:2)
07     03     01 (:3)
07     01     01 (:7)
01     01     01
KPK = 2x2x2x2x2x3x7 = 672
FPB = 2
