\(\dfrac{108}{504}=\dfrac{3}{14}\) ( cùng chia tử mẫu cho 36)

108/ 504= 108: 36/ 504: 36= 3/14

chúc bạn học tốt

đúng tick cho mik nhen

\(\dfrac{108}{504}\)= \(\xrightarrow[504:36]{108:36}\) = \(\dfrac{3}{14}\)

a) \(\frac{\left(-63\right)}{81}=\frac{\left(-63\right):9}{81:9}=\frac{-7}{9}\)

b) \(\frac{-25}{-75}=\frac{\left(-25\right):25}{\left(-75\right):25}=\frac{-1}{-3}=\frac{1}{3}\)

\(a.\frac{-63}{81}=\frac{-7}{9}\)

\(b.\frac{-25}{-75}=\frac{1}{3}\)

a,-7/9

b,1/3

a 10/ 17                      b đã là phân số tối giản

a) \(\frac{10}{17}\) 
b) Phân số b đã tối giản

a: \(\dfrac{31995-81}{42660-108}=\dfrac{31914}{42552}=\dfrac{3}{4}\)

b: \(\dfrac{3\cdot5\cdot7\cdot11\cdot13\cdot37-10101}{1212120+40404}=\dfrac{545454}{1252524}=\dfrac{27}{62}\)

a, $\frac{31995-81}{42660-108}$

= $\frac{395.81-81}{395.108-108}$

=$\frac{81.394}{394.108}$

= $\frac{81}{108}$          = $\frac{3}{4}$

b, $\frac{3.5.7.11.13.37-10101}{1212120+40404}$

= $\frac{3.5.7.11.13.37-3.7.13.37}{\mathrm{3.7.12.13.37.10}+\mathrm{3.4.7.13.37}}$

= $\frac{\left(\mathrm{3.7.13.37}\right)(5.11-1)}{\left(\mathrm{3.7.13.37}\right)(120+4)}$

= $\frac{5.11-1}{120+4}$

= $\frac{54}{124}$ = $\frac{27}{62}$

a)  36 − 48 = − 3 4

b)  − 15 50 = − 3 10

c)  − 18 − 81 = 2 9

d)  145 215 = 29 43

\(\dfrac{4}{100}=\dfrac{1}{25}\\ \dfrac{81}{54}=\dfrac{3}{2}\)

tick chi nha

cảm ơn em nhiều

27/81= (27 x 1)/(27 x 3)= 1/3
