Answer 1

$(4\frac{1}{9} \times 3.3 + 126 \frac{13}{30} ) \times 1.5 \div 60 = ( \frac{37}{9} \times \frac{33}{10} + \frac{3793}{30} ) \times \frac{1}{40} = ( \frac{407}{30 } + \frac{3793}{30} ) \times \frac{1}{40} = \frac{4200}{30} \times \frac{1}{40} = 140 \times \frac{1}{40} = \frac{7}{2} = 3 \frac{1}{2}$
