1. 8/25 × 4/4 = 24/100 = 24%

4. 90% - 35 % = 55%

7. 2/3 × 6/7 = 12/21 (disederhanakan) = 3/7

10. 12 :6 = 2 × 8 = 16

11. 25/100 × 150.000.00 = 700 = 70 (kurang tau jg moga benar ya no . 11)

Semoga Membantu :)

1.  8/25 X 100  = 32%

2.  13/20          = 0,65

3.  1 2/8 X 5/9  = 10/8 X 5/9 = 50/72 = 25/36

4.  35% + n      = 90%
                n      = 90% - 35 %
                n      = 55 %

5.  7 x 3/8        = 21/8 = 2  5/8  
 
6.  8,75 + 6,57 - 4,82  = 10,5

7.  2/3 x 6/7         = 12/21 = 4/7

8.  (30,25 : 5,5) - (6,25 :2,5) = 5,5 - 2,5 = 3

9.  2/3 : 2/5 x 1/5 = 2/3 x 5/2 x 1/5 = 10/30 = 1/3

10. 12:6/8            = 12 x 8 / 6 = 16

11. 25% x Rp150.000 = Rp37.500
