\(a,5=\dfrac{20}{4};11=\dfrac{44}{4};21=\dfrac{84}{4};200=\dfrac{800}{4};125=\dfrac{500}{4};2000=\dfrac{8000}{4}\\ b,2=\dfrac{108}{54};3=\dfrac{108}{36};108=\dfrac{108}{1};1=\dfrac{108}{108};9=\dfrac{108}{12};4=\dfrac{108}{27};6=\dfrac{108}{18}\)
1.
a) 10=\(\dfrac{40}{4}\)
b) 25= \(\dfrac{100}{4}\)
2.
a) 11=\(\dfrac{11}{1}\)
b) 276=\(\dfrac{276}{1}\)

Bài 3:
a: 1/11; 2/11; 3/11; 4/11; 5/11
b: 38/37; 40/37; 56/37; 39/37; 70/37
Bài 3:
a: 1/11; 2/11; 3/11; 4/11; 5/11
b: 38/37; 40/37; 56/37; 39/37; 70/37
\(8=\dfrac{8}{1};14=\dfrac{14}{1};32=\dfrac{32}{1};0=\dfrac{0}{1};1=\dfrac{1}{1}\)
$5 = \frac{5}{1}$ ; $14 = \frac{{14}}{1}$ ; $327 = \frac{{327}}{1}$
$1 = \frac{1}{1}$ ; $0 = \frac{0}{1}$
\(5=\dfrac{5}{1}\)
\(14=\dfrac{14}{1}\)
\(327=\dfrac{327}{1}\)
\(1=\dfrac{1}{1}\)
\(0=\dfrac{0}{1}\)
7=21/3
11=33/3
