Answer 1

No 1. kalau gak salah
1 20/24
1 5/6

Answer 2

1.) 5/4 + 2/8 + 1/3 = 5/4 + 1/4 + 1/3 = 15/12 + 3/12 + 4/12 = 22/12 = 11/6

2.) 2+4+8 + 1/8 + 1/12 + 7/6 = 15 + 3/24 + 2/24 + 28/24 = 15 33/24 = 15 11/8

3.) 3/5 - 2/6 = 18/30 - 10/30 = 8/30 = 4/15

4.) 7/13 - 5/14 = 98/182 - 65/182 = 33/182

5.) 16/6 - 3/6 = 13/6 = 2 1/6

6.) 18/4 - 2/3 = 9/2 - 2/3 = 27/6 - 4/6 = 23/6 = 3 5/6

7.) 2 - 6/7 = 14/7 - 6/7 = 8/7

8.) 6 - 14/3 = 18/3 - 14/3 = 4/3

9.) 8/9 - 1/3 - 2/6 = 8/9 - 1/3 - 1/3 = 8/9 - 3/9 - 3/9 = 2/9

10.) 81/8 - 5/6 - 27/4 = 243/24 - 20/24 - 163/24 = 61/24 = 2 13/24

11.) 2/5 x 100% = 2 x 20% = 40%

12.) 12% = 12/100 : 4/4 ( sederhanakan pecahan dg faktor 4) = 3/25

13.) 0,52 = 52/100 = 26/50 = 13/25
