f = 1,167857142857143

Answer 2

Explicație pas cu pas:

a)

$\frac{^{10)} 29,7}{1,2} = \frac{297^{(3} }{12} = \frac{^{25)} 99}{4} = \frac{2475}{100} = 24,75$

b)

$\frac{^{100)} 85,7}{0,18} = \frac{8570^{(2} }{18} = \frac{4285}{9} = 476 \frac{1}{9} = 476,(1)$

c)

$\frac{^{1000)} 0,325}{0,24} = \frac{325^{(5} }{240} = \frac{^{1875)} 65}{48} = \frac{121875}{90000} = 1 \frac{31875}{90000} = 1.3541(6)$

d)

$\frac{^{100)} 8,42}{2,7} = \frac{^{370)} 842}{270} = \frac{311540}{99900} = 3 \frac{11840}{99900} = 3,11(851)$

e)

$\frac{^{1000)} 2,456}{0,9} = \frac{2456}{900} = 2 \frac{656}{900} = 2,72(8)$

f)

$\frac{^{1000)} 0,327}{0,28} = \frac{327}{280} = 1 \frac{47}{280} = 1.167857142857...$
