Question

Vă rog frumos să mă ajuți

Answer 1

Răspuns:

a)

$\frac{25x}{100} = \frac{60}{1}$

25x = 100 × 60

25x = 6000

x = 240

b)

$\frac{50x}{100} = \frac{100}{1}$

50x = 100 × 100

50x = 10000

x = 200

c)

$\frac{75x}{100} = \frac{96}{1}$

75x = 100 × 96

75x = 9600

x = 128

d)

$\frac{90x}{100} = \frac{720}{1}$

90x = 100 × 720

90x = 72000

x = 800

e)

$\frac{15x}{100} = \frac{12}{1}$

15x = 100 × 12

15x = 1200

x = 80

f)

$\frac{175x}{100} = \frac{140}{1}$

175x = 100 × 140

175x = 14000

x = 80

g)

$\frac{125x}{100} = \frac{250}{1}$

125x = 100 × 250

125x = 25000

x = 200

h)

$\frac{4.8x}{100} = \frac{6}{1}$

4,8x = 100 × 6

4,8x = 600

x = 125

i)

$\frac{3.6x}{100} = \frac{8.1}{1}$

3,6x = 100 × 8,1

3,6x = 810

x = 225
