Answer 1

A) 100 = 100%
x = 1%
x100=100
x=100/100
x=1

B) 200 = 100%
x = 50%

X100=200×50
x100 = 10000
x=10000/100
x=100

C) 1000 = 100%
x = 10%
x100=1000×10
x= 10000/100
x=100

D) 4 = 100%
x = 25%
x100=25×4
x=100/100
x=1

E) 150 = 100%
x = 30%
x100=150×30
x=4500/100
x=45

F) 50 = 100%
x = 5%
x100=250
x=250/100
x=2.5

G) 80 = 100%
× = 2%
x100=160
x=160/100
x=1.6

H) 175 = 100%
x = 45%
x100=7875
x=7875/100
x=78.75

I) 75 = 100%
x = 33%
x100=2475
x=2475/100
x=24.75

Bons estudos!
