б)70

в)90

Answer 2

8% = 0,08

31% = 0,31

124% = 1,24

$368 \times \frac{25}{100} = 368 \times \frac{1}{4} = \frac{368}{4} = 92$

$5.8 \times 0.4 = 5 \frac{8}{10} \times \frac{4}{10} = \frac{29}{5} \times \frac{2}{5} = \frac{58}{25} = 2 \frac{8}{25} = 2.32$

$162.9 \times 0.03 = 162 \frac{9}{10} \times \frac{3}{100} = \frac{4887}{1000} = 4.887$

$18 \div \frac{20}{100} = 18 \times \frac{5}{1} = 18 \times 5 = 90$

$10.5 \div 0.15 = 10 \frac{1}{2} \times \frac{20}{3} = \frac{21}{2} \times \frac{20}{3} = 7 \times 10 = 70$

$2.7 \div 0.03 = 2 \frac{7}{10} \times \frac{100}{3} = \frac{27}{10} \times \frac{100}{3} = 9 \times 10 = 90$
