Question

Tolong jawab dari nomor 1-9 pakai cara!

Answer 1

1.) 1 3/4 = 7/4
= 7/4 x 25/25 = 175/100 
= 175%

2.) 0,5 = 5/10

3.) 6/12 = 6 : 12 = 0,5

4.) 3/4 + 4/5 = 15/20 + 16/20 = 31/20 atau dalan bentuk pecahan campuran 1 11/20

5.) 2 1/2 + 2 2/3 = 5/2 + 8/3 = 15/6 + 16/6 = 31/6 pecahan campuran = 5 1/6

6.)  1,24 + 5,58 = 124/100 + 558/100 =  682/100 dalam desimal = 6,82

7.) 2/4 - 1/3 = 8/12 = 4/12 = 4/12 = 1/3

8.) 3 4/6 - 1 2/4 = 22/6 - 6/4 = 88/24 - 36/24 = 52/24 dalam campuran = 2 4/24 = 2 1/6 

9.)  4 - 1/5 = 4/1 - 1/5 = 20/5 - 1/5 = 19/5  dalam campuran 3 4/5 

kalo no 9 saya kurang yakin
