. tolong di jawab ya
jangan gasal pisssss​ Jawab:
1 kodi =20
1 lusin =12

6 kodi = 120
2 lusin = 24

maka 120 : 24 = 20 : 4 = 5 : 1

Jawaban:

1. jeruk manis = 56 - 14= 42buah

jeruk manis : keseluruhan jeruk = 42 : 56 = 3 : 4(a)

2. 6 kodi = 6 × 20 = 120buah

2 lusin = 2 × 12 = 24 buah

120 : 24

= 10 : 2

= 5 : 1 (b)

3. s = 1 : 200

luas pd peta = 8 × 5,5 = 44cm²

js = jp : s

js = 44 : 1/200

js = 44 × 200

js = 8.800

luas sbnrny = 8.800cm² = 0,88m² (seharusnya)

4. umur Dani skrg = 27 tahun

umur dani 3 tahun lalu = 27 - 3 = 24 tahun

umur dani : umur fadi = 3 : 1

umur fandi = 1/3 × 24

= 8

8 + 3 = 11

umur fandi = 11tahun(c)

5. 180 hari => Rp 36.000.000,00

220 hari => Rp ?

220/180 × 36.000.000

= 44.000.000

pendapatan guru tsb dlm setahun = Rp 44.000.000,00 (d)

semoga membantu
