\(\frac{55}{45}\)=\(\frac{11}{9}\) nhớ k cho mk nha
\(\frac{3}{15}\)-\(\frac{5}{35}\)=\(\frac{1}{5}\)-\(\frac{1}{7}\)
\(\frac{1}{5}\)- \(\frac{1}{7}\) = \(\frac{7}{35}\)- \(\frac{5}{35}\)= \(\frac{7-5}{35}\)=\(\frac{2}{35}\)
tick nhé
\(\dfrac{90}{120}=\dfrac{30.3}{30.4}=\dfrac{3}{4}\)
\(\dfrac{15}{25}=\dfrac{5.3}{5.5}=\dfrac{3}{5}\)
\(\dfrac{18}{45}=\dfrac{9.2}{9.5}=\dfrac{2}{5}\)
\(\dfrac{36}{64}=\dfrac{4.9}{4.16}=\dfrac{9}{16}\)
\(\dfrac{32}{72}=\dfrac{8.4}{8.9}=\dfrac{4}{9}\)
\(\dfrac{84}{49}=\dfrac{7.12}{7.7}=\dfrac{12}{7}\)
\(\dfrac{90}{120}=\dfrac{3}{4};\dfrac{15}{25}=\dfrac{3}{5};\dfrac{18}{45}=\dfrac{2}{5};\dfrac{36}{64}=\dfrac{9}{16};\dfrac{32}{72}=\dfrac{4}{9};\dfrac{84}{49}=\dfrac{12}{7}\)
\(\frac{3}{4}+\frac{1}{6}=\frac{9+2}{12}=\frac{11}{12}\)
\(\frac{11}{12}-\frac{3}{4}=\frac{11-9}{12}=\frac{2}{12}=\frac{1}{6}\)
\(\frac{11}{12}-\frac{1}{6}=\frac{11-2}{12}=\frac{9}{12}=\frac{3}{4}\)
\(\frac{1}{6}+\frac{3}{4}=\frac{2+9}{12}=\frac{11}{12}\)
\(24m=\frac{24}{1000}km=\frac{3}{125}km.\)
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
\(\frac{1515}{1717}\)= \(\frac{15}{17}\)
rut gon bang 3/4
tk nha điểm hỏi đáp của mình thấp lắm
bằng \(\frac{3}{4}\) tk cho mik nha
