plisss bantu jawab yg rom 3 , 36 - 40

40.
= 5/8 × 16
= 10 kelereng Budi

=3/8 × 16
=6 kelereng Aksan

39.
=20km=2.000.000cm
=10:2.000.000
=1: 200.000 cm
skala= 1: 200.00 cm
"maaf kurang lengkap"

36. 2 2/5 + 1 1/2 - 2 3/4 = n

= (2+1-2) 8/20 + 10/20 - 15/20
= 18/20 - 15/20
= 1 3/20

Atau
= 12/5 + 3/2 - 11/4
= 48/20 + 30/20 - 55/2
= 78/20 - 55/20
= 23/20
= 1 3/20

39. 20 km = 2000.000 cm
= Jarak pada peta : jarak sebenarnya
= 10 : 2000.000
= 1 : 200.000
Jadi, skalanya adalah 1 : 200.000 cm

40. kelereng Budi = 5/8 x 16
= 5 x 2
= 10
Kelereng Aksan = 3/8 x 16
= 3 x 2
= 6
37. = 30/100 x 15000
= 4500
38. 6 4/5
= 34/5 x 8
= 54,4 liter

Maaf jika salah
