tolong dijawab ya,please!

total waktu = 48 jam

-tidur
18/48 × 100% = 37.5%

-makan
2.5/48 × 100% = 5.2%

-rekreasi
8/48 × 100% = 16.6%

-menonton tv
6/48 × 100% = 12.5%

-mengerjakan pr
2/48 × 100% = 4.16%

-bermain
2/48 × 100% = 4.16%

-lainnya
9.5/58 × 100% = 19.79%

9.a. 6/24 , .../21 , ..../28
→ 6/24 = x/21
→ 1/4 = x/21
→ 4x = 21
→ x = 5.25

sampai seterusnya caranya sama aja
