Question

considerando que 100% equivale a 300 km, responda ao que se pede

qual o valor de 2%
qual o valor de 10%
qual o valor de 50%
qual o valor de 25%

Answer 1

2% = 6 km
10% = 30 km
50% = 150 km
25% = 75 km

Answer 2

a) 300 km - 100%
     x      - 2%
100x = 300*2
100x = 600
x = 600/100
x = 6 km

b) 300km  - 100%
         x      - 10%
100x = 300*10
100x = 3000
x = 3000/100
x = 30 km 

c) 300 km  -  100%
        x        -  50%
100x = 300*50
100x = 15000
x = 15000/100
x = 150 km

d) 300km - 100%
       x       -  25%
100x = 7500
x = 7500/100
x = 75 km
