DAN JAWABAN
Jawaban:
8. 3 + 1/23 - 2,25
= 3 + 1/23 - 225/100
= 69/23 + 1/23 - 9/4
= 70/23 - 9/4
= 280/92 - 207/92
= 73/92
9. 9 - 7,5 + 6/23
= 9 - 75/10 + 6/23
= 9 - 15/10 + 6/23
= 9 - 345/230 + 60/230
= 9 - 405/230
= 9 - 81/46
= 414/46 - 81/46
= 333/46
10. 9,25 - 3/110 + 7
= 925/100 - 3/110 + 7
= 37/4 - 3/110 + 770/110
= 37/4 - 773/110
= 2.035/220 - 1.547/220
= 488/220
= 122/55
Semoga membantu^^
