pliss jawab yg bner nanti aku kasih poin 10 deh!!!

1. 40% = 24 kg
berat badan paman = 100/40 × 24 kg
= 5/2 × 24 kg = 60 kg

2. 75% × 1,5 + 2 1/2 ÷ 3/5
= (75/100×15/10) + (1/2 × 5/3)
= 1125/1000 + 5/6
= 1 1/8 + 5/6
= 9/8 + 5/6
= 27/24 + 20/24
= 47/24
= 1 23/24

3. 4,5 kg ÷ 36
= 0,125 kg tiap buah jeruk

4. luas = 30,5 m × 15,25 m
luas = 465,125 m2

5. soal ada yg tertutup tipex.
