Question

5x-3целых1/2=4 целых2/3
уронение

Answer 1

$5x - 3dfrac{1}{2} = 4dfrac{2}{3}$

$5x - dfrac{7}{2} = dfrac{14}{3}$

$5x = dfrac{^{2 cdotp/}14}{3} + dfrac{^{3cdotp/}7}{2} = dfrac{28 + 21}{6} = dfrac{49}{6}$

$x = dfrac{49}{6} : 5 = dfrac{49 cdotp 1}{6 cdotp 5} = dfrac{49}{30} = 1dfrac{19}{30}$
