Question

Замените дробью со знаменатилем 10,100 или 1000 и запишите в виде десятичной дроби следущие числа: 1/5; 1/2; 1/4; 1/8; 1/25; 1/125

Answer 1

1/5=0.2

1/2=0.5

1/4=0.25

1/8=0.125

1/25=0.04

1/125=0.008

Answer 2

$\frac{1}{5}=\frac{1*2}{5*2}=\frac{2}{10}=0,2$

$\frac{1}{2}=\frac{1*5}{2*5}=\frac{5}{10}=0,5$

$\frac{1}{4}=\frac{1*25}{4*25}=\frac{25}{100}=0,25$

$\frac{1}{8}=\frac{1*125}{8*125}=\frac{125}{1000}=0,125$

$\frac{1}{25}=\frac{1*4}{25*4}=\frac{4}{100}=0,04$

$\frac{1}{125}=\frac{1*8}{125*8}=\frac{8}{1000}=0,008$
