Tolong di jawab ya pake cara..Dengan benar jawab nya jangan asal-asalan.. Makasihh:)

3. 1,5 + 3/4 : 9 = 1,5 + 0,75 = 2,25 : 9 = 0, 25 m

4. 1 1/2 jam x 25.000 = 3/2 x 25.000 = Rp. 37.500
(disni tidak ada keterangan 25.000 per orang tp cuma per jam)

5. 2 x 25 1/2 = 51 kg
5% = 5 /100 x 51 = 255/100 = 2 55/100 = 2 11/20

51 - 2 11/20 = 51/1 - 255/100 = 5100/100 - 255/100 = 4845/100 = 48 45/100 = 48 9/20 kg

6. 50% = 50/100 x 2,5 kg = 1,25 kg
1,25 + 1 1/2 = 125/100 + 3/2 = 125/100 + 150/100 = 275/100 = 2 75/100 = 2 3/4 kg

7. buku tulis 20/100 x 25.000 = Rp. 5.000
sisa 25.000 - 5.000 = Rp. 20.000
ice cream = 1/5 x 20.000 = rp. 4.000
Celengan 20.000 - 4.000 = Rp. 16.000

8. 3/5 - 1/4 = 12/20 - 5/20 = 7/20 x 250 = 1750 /20 = 87,5 ml
