Question

scrieti sub forma de raport procentul (procent) : 5/4 4/5 3/4 0,25 0,125 13,52

Answer 1

a) 5/4 = p/100
    4p = 100*5
    p = 100*5/4 = 25*5 = 125
    Atunci 5/4 = 125/100 = 125%
b) 4/5 = p/100
    5p = 4*100
    p = 4*100/5 = 4*20 = 80
    Atunci 4/5 = 80/100 = 80%
c) 3/4 = p/100
    4p = 3*100
    p = 3*100/4 = 3*25 = 75
    Atunci 3/4 = 75/100 = 75%
d) 0,25 = 25/100 = 25%
e) 0,125 = 125/1000 = p/100
    1000p = 125*100
    p = 125*100/1000 = 125/10 = 12,5
    Atunci 0,125 = 12,5/100 = 12,5%
f) 13,52 = 1352/100 = 1352%
