\(24m=\frac{24}{1000}km=\frac{3}{125}km.\)

6 yến = \(\frac{6}{100}\)tấn = \(\frac{3}{50}\)tấn.

------------------------------------------------------------------------

\(\frac{1515}{1717}=\frac{1515\div101}{1717\div101}=\frac{15}{17}\)

24m = \(\frac{24}{1000}\)km = \(\frac{3}{125}\)km

6 yến = \(\frac{6}{100}\)tấn = \(\frac{3}{50}\)tấn

\(\frac{1515}{1717}\)= \(\frac{15}{17}\)

24m=24/1000km=3/125km

6 yến=6/100 tấn=3/50 tấn

1515/1717 = 15/17

\(\dfrac{90}{120}=\dfrac{30.3}{30.4}=\dfrac{3}{4}\)

Thêm 70 vào tử số hay mẫu số bn?

cộng 70 vào tử số ròi cộng 70 vào mẫu số rồi rmoiws rút gọn

Theo thứ tự : 5/6 ; 2/3 ; 2/3 ; 3/2 ; 2/3 ; 3/8 ; 3/1(hay là 3)

\(\dfrac{10}{12}=\dfrac{5}{6}\)        \(\dfrac{8}{12}=\dfrac{2}{3}\)        \(\dfrac{10}{15}=\dfrac{2}{3}\)        \(\dfrac{27}{18}=\dfrac{3}{2}\)        \(\dfrac{24}{36}=\dfrac{4}{6}=\dfrac{2}{3}\)

\(\dfrac{18}{48}=\dfrac{3}{8}\)        \(\dfrac{42}{14}=\dfrac{6}{2}=\dfrac{3}{1}\)

10/12 = 5/6 

8/12 = 2/3 

10/15 = 2/3 

27/18 = 3/2 

18/48 = 3/8 

42/14 = 3 

\(A=2\sqrt{27}-\sqrt{75}-\sqrt{\frac{4}{3}}\)\(=2\sqrt{9.3}-\sqrt{25.3}-\sqrt{\frac{4.3}{9}}\)\(=2.3\sqrt{3}-5\sqrt{3}-\frac{2}{3}\sqrt{3}\)\(=6\sqrt{3}-5\sqrt{3}-\frac{2}{3}\sqrt{3}\)\(=\frac{1}{3}\sqrt{3}\)\(=\frac{\sqrt{3}}{3}\)

3/8= 0.375

bằng 3 : 8 = 0,375 bn nha

k cho mik mik đầu tiên

\(\frac{124}{237}\)

124242423/237373735= 123/235 
-kết quả đúng nhất-

\(=\frac{123}{235}\)
