[tex] \frac{121}{25} \times \frac{1}{33 {}^{2} } + \frac{3}{4} \div (37 - \frac{99}{4} ) = \frac{121}{5 {}^{2} \times 3 {}^{2} \times 11 {}^{2} } + \frac{3}{4} \div ( \frac{144}{4} - \frac{99}{4} ) = \frac{1}{225} + \frac{3}{4} \div \frac{45}{4} = \frac{1}{225} + \frac{3}{4} \times \frac{4}{45} = \frac{1}{225} + \frac{1}{15} = \frac{1}{225} + \frac{15}{225} = \frac{16}{225} [/tex]
