Ada yg tau jawabannya dari no.3 sampai 7
Semoga membantugood luck
3. 16/100 +3/5+1/25
=16/100 + 60/100 + 4/100
= 80/100 = 80%
4. 7/20 +8/10 + 75/100
=35/100 + 80/100 + 75/100
=190/100 = 1,9
5. 12/25 – 1/100 -5/100
=48/100 – 1/100 – 5/100
=42/100 =0,42
6. 36/120 x 50/100 =15/100 = 0,15
7. 1 4/5 = 9/5 : 25/100
ingat tanda bagi dibalik kali & nomor akhir dibalik
= 9/5×100/25= 36/5 =7,2
okey… maaf kalau salah…
