Answer 1

а) $\frac{3}{4} + 0.8 = 0.75 + 0.8 = 1.55$

б) $1.34 - \frac{4}{25} = 1.34 - 0.16 = 0.18$

в) $\frac{3}{5} \div 15 = 0.6 \div 15 = 0.04$

г) $\frac{9}{60} \times (0.6 + 3.4) = 0.15 \times (0.6 + 3.4) = 0.09 + 0.51 = 0.6$

д) $( \frac{2}{5} + 0.7) \div 11 = (0.4 + 0.7) \div 11 = 1.1 \div 11 = 0.1$

е) $( \frac{7}{4} - 0.25) \times 27 = (1.75 - 0.25) \times 27 = 1.5 \times 27 = 40.5$
