Question

de % calculo completo:

a-8% de 60= f-15% de 120=
b-8% de 50= g-13% de 200=
c-30% de 600= h-43% de 100=
d-50% de 900= i-40% de 150=
e-20% de 300=

gente mesmo que demore eu presciso eu tenho que entregar amanha!!!

Answer 1

$a- \frac{8}{100} = \frac{x}{60} \\ 100x=480 \\ x= \frac{480}{100} \\ x=4,8$
$b- \frac{8}{100} = \frac{x}{50} \\ 100x=400 \\ x= \frac{400}{100} \\ x=4$
$c- \frac{30}{100} = \frac{x}{600} \\ 100x=18000 \\ x= \frac{18000}{100} \\ x=180$
$d- \frac{50}{100} = \frac{x}{900} \\ 100x=45000 \\ x= \frac{45000}{100} \\ x=450$
$e- \frac{20}{100} = \frac{x}{300} \\ 100x=6000 \\ x= \frac{6000}{100} \\ x=60$
$f- \frac{15}{100} = \frac{x}{120} \\ 100x=180 \\ x= \frac{180}{100} \\ x=1,8$
$g- \frac{13}{100} = \frac{x}{200} \\ 100x=2600 \\ x= \frac{2600}{100} \\ x=26$
$h- \frac{43}{100} = \frac{x}{100} \\ 100x=4300 \\ x= \frac{4300}{100} \\ x=43$
$i- \frac{40}{100} = \frac{x}{150} \\ 100x= 6000 \\ x= \frac{6000}{100} \\ x=60$
