Jawaban :

 

3 8/25 + 25% + 4,6

= 3 8/25 + 25/100 + 46/10 = 83/25 + ¼ + 23/5 = 1.660/500 + 125/500 + 2.300/ 500 = 4.085/500 = 8 85/500 = 817/100

      

3 8/25 =[ (25 x3) + 8]/25 = (75 + 8)/25 = 83/25

25% = 25/100


4,6 =46/10


83/25 + 25/100 + 46/10 = (83 x 4)/(25 x 4) +25/100 + (46 x 10)/(10 x 10) = 332/100 + 25/100 + 460/100 =817/100

jawab : 817/100 (pecahan biasa)
