Question

Cum se calculeaza procentul numerelor 1,2,3,4,5,7 din 25?? Va rog, e urgent!!!

Answer 1

X % din 25 = 1

X / 100 × 25 = 1

X / 100 = 1 : 25

X / 100 = 0, 04

X = 0, 04 × 100

X = 4

______________________________

X % din 25 = 2

X / 100 × 25 = 2

X / 100 = 2 : 25

X / 100 = 0, 08

X = 0, 08 × 100

X = 8

______________________________

X % din 25 = 3

X / 100 × 25 = 3

X / 100 = 3 : 25

X / 100 = 0, 12

X = 0, 12 × 100

X = 12

______________________________

X % din 25 = 4

X / 100 × 25 = 4

X / 100 = 4 : 25

X / 100 = 0, 16

X = 0, 16 × 100

X = 16

______________________________

X % din 25 = 5

X / 100 × 25 = 5

X / 100 = 5 : 25

X / 100 = 0, 2

X = 0, 2 × 100

X = 20

______________________________

X % din 25 = 7

X / 100 × 25 = 7

X / 100 = 7 : 25

X / 100 = 0, 28

X = 0, 28 × 100

X = 28
