\(M=\frac{2.2^{12}.3^6+2^2.2^9.3^9}{2^5.2^7.3^7+2^7.2^3.3^{10}}\)
\(=\frac{2^{11}.3^6\left(2^2+3^3\right)}{2^{10}.3^7\left(2^2+3^3\right)}\)
\(=\frac{2}{3}\)

\(M=\frac{2.\left(2^3\right)^4.\left(3^3\right)^2+2^2.\left(2.3\right)^9}{2^5.\left(2.3\right)^7+2^7.2^3.\left(3^2\right)^5}\)
\(M=\frac{2.2^{12}.3^6+2^2.2^9.3^9}{2^5.2^7.3^7+2^7.2^3.3^{10}}\)
\(M=\frac{2^{13}.3^6+2^{11}.3^9}{2^{12}.3^7+2^{10}.3^{10}}\)
\(M=\frac{2^{11}.3^6\left(2^2.1+1.3^3\right)}{2^{10}.3^7\left(2^2.1+1.3^3\right)}\)
\(M=\frac{2.31}{3.31}\)
\(M=\frac{2}{3}\)

cả 2 lần bán được là :
1/4 + 2/5 = 13/20 ( số trứng )
vì số trứng còn lại là 21 quả => 21 quả = 7/20 ( số trứng )
số trứng có ban đầu là : 21 : 7/20 = 60 ( quả trứng )
lần thứ nhất bán được là : 60 x 1/4 = 15 ( quả )
lần thứ 2 bán được số trứng là : 60 x 2/5 = 24 ( quả )
đáp số : ...
