0,4
0,7
0,020
0,81
0,009
2,34
2,663

Answer 1

4/10= 0,4
7/10= 0,7
20/1000 = 0,020
81/100 = 0,81
234/100 = 2,34
2663/1000 =2,663

Answer 2

$0,4 = \dfrac{4}{10}= \dfrac{4/2}{10/2}=\dfrac{2}{5}$

$0,7= \dfrac{7}{10}$

$0,020= \dfrac{20}{1000}= \dfrac{20/20}{1000/20}=\dfrac{1}{50}$

$0,81= \dfrac{81}{100}$

$0,009= \dfrac{9}{1000}$

$2,34= \dfrac{234}{100}= \dfrac{234/2}{100/2}=\dfrac{117}{50}$

$2,663= \dfrac{2663}{1000}$


Bons estudos!
