Answer 1

Resposta:
A) 450 — 100%
X — 15%
100x = 450.15
100x = 6750
X = 6750/100
X = 67,50

B) 460 — 100%
X — 1,5%
100x = 460.1,5
100x = 690
X = 690/100
X = 6,9

C) 460 — 100%
X — 0,15%
100x = 460.0,15
100x = 69
X = 69/100
X = 0,69

D) 460 — 100%
X — 0,015%
100x = 460.0,015
100x = 6,9
X = 6,9/100
X = 0,069
