Ответ:

$a \div b \div c = 7 x\div 5 x\div 9x \\ 7x + 5x + 9x = 42 \\ 21x = 42 \\ x = 2 \\ a = 14 \\ b = 10 \\ c = 18$

$c = 27 \\ \frac{27}{9} = 3 \\ b = 3 \times 5 = 15 \\ a = 3 \times 7 = 21$

$5x + 9x = 84 \\ x = 6 \\ a = 42 \\ b = 30 \\ c = 54$

$ae \times be = ce \times de \\ \\ 36 = x \times 4x \\ x = 3 \\ ce = 3 \\ de = 3 \times 4 = 12$

${mk}^{2} = mf \times me \\ mf = 10 \times 10 \div 20 = 5$
