6=30/5

7=35/5

8=40/5

9=45/5

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

giúp mik với ạ!!!

9b=63b/7

\(6=\dfrac{12}{2}\)

\(9=\dfrac{18}{2}\)

\(4=\dfrac{8}{2}\)

\(12=\dfrac{24}{2}\)

\(11=\dfrac{22}{2}\)

\(10=\dfrac{20}{2}\)

\(13=\dfrac{26}{2}\)

\(23=\dfrac{46}{2}\)

\(30=\dfrac{60}{2}\)

\(10=\dfrac{10\cdot6}{6\cdot1}=\dfrac{60}{6}\)

\(6=\dfrac{6\cdot6}{1\cdot6}=\dfrac{36}{6}\)

\(101=\dfrac{101\cdot6}{6}=\dfrac{606}{6}\)

\(9=\dfrac{9\cdot6}{6}=\dfrac{54}{6}\)

\(22=\dfrac{22\cdot6}{6}=\dfrac{132}{6}\)

\(\dfrac{435}{113}\)viết dưới dạng phép chia có dư là: đc 3 dư 96

các phân số lớn hơn 1 là : \(\dfrac{9}{8};\dfrac{19}{17};\dfrac{27}{24}\)

các phân số nhỏ hơn 1 là

\(\dfrac{13}{17};\dfrac{5}{6}\)

$5 = \frac{5}{1}$  ;   $14 = \frac{{14}}{1}$   ;   $327 = \frac{{327}}{1}$

$1 = \frac{1}{1}$  ;   $0 = \frac{0}{1}$

\(5=\dfrac{5}{1}\)

\(14=\dfrac{14}{1}\)

\(327=\dfrac{327}{1}\)

\(1=\dfrac{1}{1}\)

\(0=\dfrac{0}{1}\)

1.
a) 10=\(\dfrac{40}{4}\)

b) 25= \(\dfrac{100}{4}\)

2.

a) 11=\(\dfrac{11}{1}\)

b) 276=\(\dfrac{276}{1}\)

c) 158=\(\dfrac{158}{1}\)

3.

\(\dfrac{1}{1};\dfrac{2}{2};\dfrac{3}{3};\dfrac{4}{4};\dfrac{5}{5}\)
