1.) 9,5 m + 25 dm =9,5 x 100 + 25 x 10 =
950 + 250 = 1200 cm
2.) 16 hm - 7,5 dam =
16 x 100 - 7,5 x 10 =
1600 - 75 = 1525 m
3.) 85,5 dam - 8 dm - 125 cm =
85,5 x 1000 - 8 x 10 - 125 =
85500 - 80 - 125 = 85295 cm
4. Faktor" :
50 = 2 x 5^2
80 = 2^4 x 5
FPB : ambil faktor yang sama dan pangkat terkecil
= 2 x 5
= 10
KPK : ambil faktor yg sama dan beda, untuk faktor yg sama ambil pangkat terbesar
= 2^4 x 5^2
= 400
5.) 6 abad + 25 dasawarsa - 10 lustrum =
6 x 100 + 25 x 10 - 10 x 5 =
600 + 250 - 50 =
800 tahun
6.) 4 dekade + 8 windu + 12 caturwulan =
4 x 10 + 8 x 8 + 12/4 =
40 + 64 + 3 =
107 tahun
semoga membantu:)
= ( 9,5 m × 100 ) + ( 25 dm × 10 )
= 950 cm + 250 cm
= 1.200 cm
2. 16 hm - 7,5 dam = ... m
= ( 16 hm × 100 ) - ( 7,5 dam × 10 )
= 1600 m - 75 m
= 1.525 m
3. 85,5 dam - 8 dm - 125 cm = ... cm
= ( 85,5 dam × 1000 ) - ( 8 dm × 10 ) - 125 cm
= 85.500 cm - 80 cm - 125 cm
= 85.420 cm - 125 cm
= 85.295 cm
4. 50 : 2 = 25 : 5 = 5
80 : 2 = 40 : 2 = 20 : 2 = 10 : 2 = 5
50= 2×5×5
80= 2×2×2×2×5
atau
KPK=
FPB=
yang 5 sama 6 nggak bisa...
maaf ya... ^_^
