\(\frac{1}{2}-\frac{1}{3}=\frac{3}{6}-\frac{2}{6}=\frac{1}{6}\)
\(\frac{1}{4}\cdot\frac{1}{5}=\frac{1}{20}\)
\(\frac{1}{9}+\frac{1}{8}=\frac{8}{72}+\frac{9}{72}=\frac{17}{72}\)
\(\frac{1}{2}:\frac{1}{8}=\frac{1}{2}\cdot8=4\)
1/2 - 1/3 = 1/6
1/4 x 1/5 = 1/20
1/9 + 1/8 = 17/72
1/2 : 1/8 = 8/2 = 4
Mn ơi ủng hộ mik nhé !
1/2-1/3=3/6-2/6=1/6
1/4x1/5=1/20
1/9+1/8=8/72+9/72=17/72
1/2:1/8=1/2x8=8/2=4
CHO MK XIN CÁI NẾU ĐÚNG!
\(\frac{1}{2}-\frac{1}{3}=\frac{3}{6}-\frac{2}{6}=\frac{1}{6}\)
\(\frac{1}{4}\times\frac{1}{5}=\frac{1\times1}{4\times5}=\frac{1}{20}\)
\(\frac{1}{9}+\frac{1}{8}=\frac{8}{72}+\frac{9}{72}=\frac{17}{72}\)
\(\frac{1}{2}:\frac{1}{8}=\frac{1}{2}\times8=\frac{1\times8}{2}=\frac{8}{2}=4\)
