  4. 5% = 
  5. 34,125 : 6 = 5,6875
  6. 35% + 2× (0,25) = 0,85
  7. 10,125 – 34,125 = – 34
  8. 2,5:- 1 × 20% = – 0,5
  9. 20% X 434 = 86,8
  10. 4× 0,4 – 1 = 0,6

 

Penjelasan dengan langkah-langkah:

35% + 2× (0,25) =   + 2 x 0,25

35% + 2× (0,25) = 0,35 + 0,5 = 0,85

 

2,5:- 1 × 20% = 2,5 : (-1) x 0,2

2,5:- 1 × 20% = – 2,5 x 0,2 = – 0,5

 

20% X 434 =  x 434

20% X 434 =  = 86,8

 

4× 0,4 – 1 = 1,6 – 1 = 0,6
