Question

1.Aflati 30/100 din 5000 lei.
2.Aflati 2/3 din 60 kg.
3.Aflati fractia a/b echivalenta cu fractia 3/5 stiind ca a x b=60.
4.Simplificati cu 6 fractiile: 6/12,24/36,42/60,96/30,18/54.

Answer 1

30/100 din 5000=30x5000:100=1500 lei
2/3 din 60=2x60:3=40=4 kg
3).a/b=3/5
axb=60
6/10=3/5

4).6/12=1/2
24/36=4/6
42/60=7/10
96/30=16/5
18/54=3/9

Answer 2

1) 5000x30:100=150000:100=1500

2) 60:3x2=20x2=40

3) a/b=3/5
    axb=60 
    6x10=60
   a=6
   b=10
   6/10=3/5

4) 6/12 = 1/2
    24/36 = 4/9
   42/60 = 7/10
   96/30 = 16/5
   18/54 = 3/9
