Answer 1

[tex] 30 +( 0.25 \times 5\%) - (3\frac{1}{2} \div \frac{1}{5} ) \\ \\ = \frac{30}{1} + ( \frac{ \cancel{25}}{100} \times \frac{5}{ \cancel{100} ^{4} } ) - ( \frac{7}{2} \times \frac{5}{1} ) \\ \\ = \frac{30}{1} + ( \frac{1}{ \cancel{100} ^{20} } \times \frac{ \cancel5}{4} ) - ( \frac{7}{2} \times \frac{5}{1} ) \\ \\ = \frac{30}{1} + \frac{1}{80} - \frac{35}{2} = \frac{2.400 + 1 - 1.400}{80} \\ \\ = \frac{1.001}{80} = 12 \frac{41}{80} [/tex]
