1. 2 1/2 + 1/2 = 2. 5/8 : 10/4 = 3. 45% + 3/4 = 4. 0,75 - 1/2 = 5. 0,45 x 1,5 = Silahkan Dijawab !!!!!

2 1/2+1/2=5/2+1/2=3
45%+3/4=45%+75%=120%
0,75-1/2=0,75-0,50=0,25
0,45×1,5=0,675
Maap klo slh y:)

4.) 75/100 - 1/2 = 75/100 - 50/100 = 25/100 : 25/25 = 1/4
.
.
5.)45/100 × 15/10 = 675/1000 : 5/5 = 135/20: 5/5 = 27/4 = 6 3/4 <---- dijadikan pecahan campuran
