3.5/4-3/2+0,14
4.15/100×7/3
tolong jawab pake caranya ya
hasilnya ke persen, pecahan biasa, pecahan desimal

Answer 1

Jika Persen......
1. 15% + 25% = 40%
2. 120% x 75% = 90%
3. 125% - 150% + 14% = - 11%
4. 15% x 233.33%
Jika Desimal......
1. 0,15 + 0,25 = 0,40
2. 1,2 x 0,75 = 0,9
3. 1,25 - 1,5 + 0,14 = - 0,11
4. 0,15 x 2,33 = 0,3495
Jika Pecahan .......
1. 15/100 + 1/4
= 3/20 + 5/20 = 8/20
2. 120/100 x 75/100
= 6/5 x 3/4 = 18/20 = 9/10
3.5/4 - 3/2+ 14/100
= 5/4 - 6/4 + 7/50
= 125/100 - 150/100 + 14/100 = - 11/100
4.15/100 x 7/3 = 3/20 x 7/3 = 21/60
