tolong donk buat besok nih kalau bisa dua dua nya ya nanti aku jafi pengikut kalian deh kalau bisa jawab no 3 sama 4 ini

isi no 3. 66/11= 6        no 4 = 7/30dibagi 1/ 25 =175/ 30 dikurangi 16/5=15/30

No 3 = (18÷(-2)+15×5)÷(6÷3×5,5)
=(-9+75)÷11
=66÷11=6
No 4 = 5 1/3 - (1/10+2/15) ÷ 1/25
= 5 1/3 - (3/30+4/30)÷1/25
= 5 1/3 - 7/30 ÷ 1/25
= 5 1/3 - 175/30
= 5 1/3 - 5 5/6
= 5 2/6 - 5 5/6
= 3/6
= 1/2

Maaf kalo salah
