a)
[tex] \frac{6}{100} \times x = 35[/tex]
• = înmulțit
[tex] \frac{6x}{100} = 35[/tex]
6x = 35 • 100
6x = 3500
[tex]x = \frac{3500}{6} [/tex]
x = 583,(3)
b)
[tex] \frac{80}{100} \times x = 240[/tex]
[tex] \frac{80x}{100} = 240[/tex]
[tex]80x = 240 \times 100[/tex]
[tex]80x = 24000[/tex]
x = 24000 : 80
x = 300
c)
[tex] \frac{1}{100} \times x = 202[/tex]
[tex] \frac{x}{100} = 202[/tex]
[tex]x = 202 \times 100[/tex]
[tex]x = 20200[/tex]
d)
[tex] \frac{0.5}{100} \times \: x = 4[/tex]
[tex] \frac{0.5x}{100} = 4[/tex]
[tex]0.5x = 4 \times 100[/tex]
[tex]0.5x = 400[/tex]
[tex]x = \frac{400}{0.5} [/tex]
[tex]x = 800[/tex]
sper ca ți-am fost de ajutor
