15/6 : 3/8 * 3/4
= 3*5/2*3 * 8/3 * 3/4
= 5*3*4
= 60
nha
\(\frac{15}{6}:\frac{3}{8}x\frac{3}{4}\)
\(=\frac{15}{16}x\frac{3}{4}\)
\(=\frac{45}{64}\)
nhé bạn
= \(\frac{15}{6}:\frac{3}{8}.\frac{3}{4}\)=
= \(\left(\frac{15}{6}:\frac{3}{8}\right).\frac{3}{4}=\frac{20}{3}.\frac{3}{4}=\frac{20.3}{3.4}=\frac{60}{12}=5\)
